Cisco Unified CallManager extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices, voice-over-IP VoIP gateways, and multimedia applications. Additional services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco Unified CallManager APIs.

The product started its life as Multimedia Manager 1. The Multimedia Manager product was designed to be the signaling controller for a point-to-point video solution. Multimeda Manager 1. Selsius-CallManager 2. Clustering was introduced at this time and [MGCP] support was added. The product was released as Cisco CallManager 3. There were a wide array of new features for this release that can be referenced in the Cisco CallManager 3.

Product version and revision changes are introduced. This revision supported more gateway devices, IP phone devices and added more enhancements and features. Building from the previous 3. In addition to the various bug fixes found in most product releases additional support for QSIG was added.

Improved H. Cisco made a large scale release with CallManager 4. Included in this release were numerous new features. Previously IP phones were restricted to only 2 calls per any given line appearance. This caveat was eliminated and IP phones could now have a user configurable maximum up to number of calls per line appearance. Other features and enhancements of note added during this release were, Hunt group, Malicious call identification, Immediate diversion, Privacy for shared lines and Call barge.

Improved security with media encryption between phones, Multi Level Administration MLA allowed delegated administration and Direct transfer allowed a user to select two calls from the same line and connect them together. Call join allowed users to select several calls from a line and conference them together.

Later in the same year Cisco released a minor platform revision as CallManager 4. This version focused on improved stability and support for even more features. Several utility tools were added as well. Additionally, some of the new features of CCM 4. The Dialed number analyzer DNA was also introduced which allowed administrators to analyze how dialed strings route calls.

Now, back to the no audio issues What is it? A one-way audio call is when you have a call between 2 phones internal-internal or internal-externaland one of them cannot hear the other end. How do I fix it? Before you start thinking about fixing that, you need to understand what is going on, how does it works, and what causes this problem. So, first of all, you may get reports from end-users about one way or no way audio or maybe "ghost calls". Sometimes the users even refer to these as "dropped calls" because they get a call, there is no audio and after a few seconds they hear reorder tone, fast busythis happens because the caller cannot hear the called phone and it's getting dead air and hang up, or maybe they can hear the other end, but realize that the called phone cannot hear them and hang up.

If this is traversing a WAN make sure you get a packet capture from the incoming and outgoing interfaces of the router and make sure the size of the incoming packet is less than the specified size for the WAN link, this can be a problem if there is a mid-call RE-INVITE with a large SDP, that could lead to audio re-negotiation issues.

Finally, if you see the phone is receiving packets but nothing can be heard on the phone you will need to get a packet capture from the phone to further analyse the RTP stream, if the packets have the wrong sequence the phone will not play those, or if Wireshark indicates that the packets are corrupted or malformed the phone might not play them, if the RTP packets are there and you can play them using Wireshark, G.

Collecting a packet capture from a Cisco IP Phone:. Setup Wireshark to create a new file every 50 MB and keep a buffer of 15 files, after this the files start being overwritten :. What if this is random and no captures were set for the phones that presented the issue?

The infrastructure layer carries data, voice, and video between all network devices and applications. This layer also provides high availability, management, quality of service QoSand network security. Call control layer : The call control layer provides for call processing, device control, and administration of the dial plan and features. Call processing is physically independent from the infrastructure layer. Applications layer : Applications are independent from call-control functions and the physical voice-processing infrastructure.

Applications, including those listed here, are integrated through IP, which allows the applications to reside anywhere within the network:. The MeetingPlace product integrates lecture-style conferences with scalable collaboration and control tools.

If you are having configuration problems using this list, contact Cisco technical support for assistance. Some ports change from one release to another, and future releases may introduce new ports.

Therefore, make sure that you are using the correct version of this document for the version of Cisco Unified Communications Manager that is installed. While virtually all protocols are bidirectional, directionality from the session originator perspective is presumed. In some cases, the administrator can manually change the default port numbers, though Cisco does not recommend this as a best practice. Be aware that Cisco Unified Communications Manager opens several ports strictly for internal use.

Installing Cisco Unified Communications Manager software automatically installs the following network services for serviceability and activates them by default.

Refer to Table 1 for details:. Configuration of firewalls, ACLs, or QoS will vary depending on topology, placement of telephony devices and services relative to the placement of network security devices, and which applications and telephony extensions are in use.

Also, bear in mind that ACLs vary in format with different devices and versions. Port values for multicast MOH are not provided because the administrator specifies the actual port values. The Ephemeral port range for the system is — Port used by the server that handles DNA initialization.

It does not constitute a port as indicated in the column heading. You can configure these ports on a per-service basis. Cisco Unified Communications Manager only uses although other devices use the full range. These protocols numbers carry encrypted IPSec traffic. They do not constitute a port as indicated in the column heading. Cisco Unified Communications Manager Attendant Console AC server line state port receives ping and registration message from, and sends line states to, the attendant console server.

Additional services in the field of data, voice, and videos, such as converged messaging, multimedia conference, collaborative contact centers, and interactive multimedia response systems, interact via CUCM application programming interface API and IP-telephony solution. The following functions are provided by CUCM:. After the call has been set up, CUCM is not involved in a call.

If during the call period the CUCM server were unplugged, users would never notice it unless they were trying to use a feature on the phone. CUCM is only involved in the setting up, teardown and functionality of the call. The user listens to the dial tone on phone A and begins to dial phone B. Digital analysis of the dialed digits is carried out by CUCM.
