Hence, the GUI files posted under the name cme-gui Unified CME Release It is mandatory to configure the command supplementary-service media-renegotiate under voice service voip configuration mode to enable the supplementary features supported on Unified CME.
Configure the CLI commands no supplementary-service sip refer , no supplementary-service sip moved-temporarily under voice service voip configuration mode for call transfer and call forward scenarios in Unified CME.
Cisco Unified CME allows small business customers and autonomous small enterprise branch offices to deploy voice, data, and IP telephony on a single platform for small offices, thereby streamlining operations and lowering network costs. Cisco Unified CME is ideal for customers who have data connectivity requirements and also have a need for a telephony solution in the same office.
The ability to deliver IP telephony and data routing by using a single converged solution allows customers to optimize their operations and maintenance costs, resulting in a very cost-effective solution that meets office needs. Ephone or voice register pool—A software concept that usually represents a physical telephone, although it is also used to represent a port that connects to a voice-mail system, and provides the ability to configure a physical phone using Cisco IOS software. Each phone can have multiple extensions associated with it and a single extension can be assigned to multiple phones.
Maximum number of ephones and voice register pools supported in a Cisco Unified CME system is equal to the maximum number of physical phones that can be connected to the system. Directory number—A software concept that represents the line that connects a voice channel to a phone. A directory number represents a virtual voice port in the Cisco Unified CME system, so the maximum number of directory numbers supported in Cisco Unified CME is the maximum number of simultaneous call connections that can occur.
This concept is different from the maximum number of physical lines in a traditional telephony system. Devices send license usage to CSSM either directly or use an on-premises satellite. CSSM shows license usage across all devices that you register to a virtual account.
A Virtual Account License Inventory displays the quantity of licenses that you purchase, those licenses in use, and a balance. Alert Insufficient Licenses is displayed if the license balance is below 0.
To avoid unnecessary reporting while you configure Unified CME, license usage is reported three minutes after the last configuration change. Use the license smart enable command to enable Smart Licensing. To disable Smart Licensing, use the no form of the command and reaccept the EULA using the license accept end user agreement configuration command.
Smart Licensing is mandatory from this release. Routers configured to use Smart Licensing offer a day evaluation period, during which you can use all the features without registering to CSSM.
You can obtain the registration token from the virtual CSSM account or from an on-premises satellite. Once registered, the evaluation period pauses and you can use the balance later.
You cannot renew the evaluation period on its expiry. Cisco Unified Communications Manager Express shuts down when the router is unregistered and allowed to pass into the Evaluation Expired state. Upon successful registration, the device sends an authorization request to CSSM for the licenses in use. Post successful authorization of the request, licenses are bound to the requesting device until the next authorization request submission.
An authorization request is sent every 30 days or when there is any change in license consumption, to maintain the registration with CSSM. The authorization expires if you do not update the license request for the router within 90 days. The certificate issued to identify the router at the time of registration is valid for one year and renewed every six months.
To reserve specific licenses for a device, generate request code from the device. Enter the request code in CSSM along with the required licenses and their quantity, and generate authorization code.
The reservation may be updated before or after the software upgrade. This release introduces a new paradigm for tracking license usage across your business.
In earlier releases, license authorization was forward looking, binding licenses to a device until the next authorization request. Actual license usage during the proceeding reporting period is now sent to CSSM, allowing you to plan ongoing license requirements based on historical usage data.
Initial device registration is no longer required to use most platform functionality and the evaluation period is deprecated. License usage reports are submitted periodically according to a minimum reporting policy set for your account. After the user listens to voicemail, the light turns off. This is the procedure to configure the MWI ephone-dns:. Enter the command ephone-dn in order to create the extensions for the Cisco IP phone lines. Enter the command number number in order to associate a telephone or extension with the ephone-dn.
Enter the command mwi [on off] in order to configure specific ephone-dns to receive MWI notification from an external voicemail system. Note : Repeat the same procedure in order to create an extension with the MWI off. From now on, most of the configurations need to be made on the actual NM-Cisco Unity Express module, which means that a connection needs to establish from the router to module. This is the procedure to configure voicemail:. Enter the command ccn application voicemail in order to enter the application configuration for voicemail.
Enter the command description "text" in order to enter a description of the application. Enter the command maxsessions number in order to specify the number of subscribers who can access this application simultaneously. Enter the command exit in order to finish the application configuration.
Enter the command exit in order to finish the configuration mode. The Auto-Attendant application permits the system to have an auto operator answer the calls and gives the caller different options to choose from a menu. For example, if the Cisco Unity Express systems has an auto attendant, the caller listens to a welcome greeting and then they are able to choose the option in order to be transferred to a specific department for example, sales, HR and so forth or a specific person for example, John Smith, Alex Lewis and so forth.
This procedure provides a configuration for Auto-Attendant:. Enter the command ccn application autoattendant in order to specify the application to configure. Enter the command maxsessions number in order to specify the number of callers who can access this application simultaneously. Enter the command parameter "name" "value" in order to specify the parameter for the application.
After the voicemail and Auto-Attendant are configured, the system must be configured to start the voicemail, and Auto-Attendant applications when a specific signal or trigger is invoked. The trigger is a telephone number. When a caller dials a specified telephone number, the SIP subsystem starts the voicemail or Auto-Attendant. This procedure configures SIP triggers for voicemail:. Enter the command ccn trigger sip phonenumber number in order to specify the telephone number that acts as the trigger configuration mode.
The number value can match one of the patterns configured in the destination-pattern field of the SIP dial peer that points to Cisco Unity Express. Enter the command application string in order to specify the name of the application to start when the trigger is entered. Enter the command enabled in order to enable the trigger. Enter the command maxsessions number in order to specify the maximum number of callers that the application can handle simultaneously.
Enter the command exit in order to finish the trigger configuration. Note : Repeat this process for the Auto-Attendant and promptmgmt applicaton. Users and groups can be created to use the system. All the people who have extensions and access voicemail must be users. An administrator user is created by default when you first access Cisco Unity Express.
This administrator cannot be assigned a voice mailbox. However, the administrator is able to configure the system, which includes the voicemail and Auto-Attendant application.
This procedure creates a user and assigns a telephone number:. Enter the command username userid create in order to create a subscriber with the specified user ID. Enter the command username userid phoneumber number in order to specify the extension for this subscriber. Note : Repeat this process in order to register as many users as you need, which does not exceed the limit supported the Cisco Unity Express system.
Make sure you assign a password and a pin to the administrator user in order to be able to configure Cisco Unity Express and make changes to it.
Assign a voice mailbox to a subscriber in order to configure a Cisco Unity Express database. A mailbox subscriber is a user created in the previous section. Not all the subscribers or extensions require a voice mailbox such as an administrator user.
Consider the function or purpose of the subscriber or extension before you assign the mailbox in order to use mailboxes efficiently. Voicemails are not compressed and use the G. Each second of G. This list shows a storage capacity summary for each Cisco Unity Express module type:. In this configuration, you create a personal mailbox.
A personal mailbox is assigned to a specific subscriber and is accessible only by this subscriber. When a caller leaves a message in this mailbox, the message waiting indicator MWI light turns on. Complete these steps in order to configure voice mailboxes:.
Enter the command voice mailbox owner name in order to create a mailbox for the name value. Enter the command description "text" in order to give a description of the mailbox. Enter the command enable in order to activate the new mailbox or reactivate the disabled mailbox. Enter the command expiration time days in order to set the number of days for which messages are stored in the mailbox. The default is 30 days. Enter the command mailboxsize seconds in order to specify the storage size of the mailbox in seconds.
Enter the command messagesize seconds in order to specify the maximum size of an incoming message, in seconds. Enter the command end in order to finish the mailbox configuration. Note : Repeat this procedure for every user that needs a voice mailbox. Check in order to see if the Cisco CallManager Express configuration misses any of the configuration commands mentioned in this document. If the configuration is correct, the Cisco CallManager Express router might miss the default-gateway configuration.
This might happen if the administrator reloads the router without saving the configuration. This errror message is also seen when the administrator decides to change the Cisco CallManager Express web administrator username and password , and the new name and password is not updated in the Cisco Unity Express system.
Use the procedure mentioned in in order to update the system with new Cisco CallManager Express username and password. Note : A reboot of the Cisco Unity Express module does not require a reboot of the router. The Cisco Unity Express module and the router can be rebooted independently of each other. However, if you reboot the router, no calls reach the module until IP connectivity is reestablished between the router and the module.
Always perform a shutdown of the module before you power-cycle the router in order to avoid data loss or file corruption. IP Phone 2 is configured to have call-forward busy and call-forward noan forwarded to the Cisco Unity Express voice mail. When the Cisco Unity Express is up, everything works as expected.
In order to resolve this issue, configure SIP retry invite to a lower value other than the default value of six. In order to fix this issue, you need to issue these commands:.
The CUE clock is not displaying accurate time. However, CallManager Express displays the correct time. You should see that the clock is synchronized. In order to overcome this problem, configure the cptone GB command under the appropriate voice port in the voice gateway.
This is an example output:. Note : The ringback tone is generated by the voice gateway. With the ephone-hunt command configured, the call does not get transferred to the CUE VM system after the final dn, and the caller receives a busy tone. In order to fix the problem, increase the max-redirect to the desired value. This issue can occur if the ephone-hunt command is configured with hops that are more than what is specified in the max-redirect command.
This is an example configuration of ephone-hunt and max-redirect :. Note : Sample output omitted. Skip to content Skip to search Skip to footer. Available Languages.

Refer to the Cisco Technical Tips Conventions for more information on document conventions. SIP is an ASCII based, application-layer control protocol that can be used to establish, maintain, and terminate calls between two or more endpoints.
SIP has rapidly emerged as the standard protocol used in IP communications, because it is a multimedia protocol that can be used for video sessions and instant messaging in addition to voice. Also, SIP can handle conference sessions and broadcasts, as well as one-to-one sessions. SIP has great potential in transforming and developing the way people communicate.
For this reason, Cisco has and continues to play an important role in taking a leadership to create new technologies that make SIP and its applications the standard of IP communications.
In order to access the IP network using a SIP trunk, it is necessary that configurations be made on the service provider, as well as on the customer side. The reason is that a customer faces challenges in handling different interpretation and implementations of SIP by equipment vendors, delivering security, managing quality of service QoS , enabling Network Address Translation NAT and firewall traversal, and ensuring carrier-grade reliability and continuity of service.
CME permits small and medium businesses to deploy voice, data, and video on a single platform. Therefore, by using CME, small and medium businesses can deliver IP telephony and data routing using a single converged solution with minimal costs.
A DTMF distortion existed between the two devices. When CME 3. Another important aspect to consider when you set up an SIP trunk is the codecs supported. Codecs represent the pulse-code modulation sample for signals in voice frequencies. SIP trunks support these codecs: G.
