An annunciator, an SCCP device that uses the Cisco Media Streaming Application service, enables Cisco Unified Communications Manager to play prerecorded announcements (.wav files) and tones to Cisco Unified IP Phones and gateways. The system automatically displays the preconfigured server (servers get added at installation). Cisco Unified Communications Manager automatically provides a set of prerecorded annunciator announcements when youContinue reading “Media Resources – Annunciator”

A media termination point (MTP) is an entity that accepts two full-duplex media streams. It bridges the streams together and allows them to be set up and torn down independently. The streaming data received from the input stream on one connection is passed to the output stream on the other connection, and vice versa. AnContinue reading “Media Resources – MTP”

A transcoder is a device that performs codec conversion, converting an input stream from one codec into an output stream that uses a different codec. For example, a transcoder can take a G.711 stream and convert it to a G.729 stream in real time. When the two endpoints in a call use different voice codecs,Continue reading “Media Resources – Transcoder”

Partition: Partitions can be seen as a collection of route patterns. Directory numbers, route patterns, and translation patterns can all belong to specific partitions. CSS(Calling Search Space): CSS’es are an ordered list of route partitions and they determine which partitions calling devices must search when they attempt to complete a call. In order to reachContinue reading “CSS and Partition”

CUCM uses Informix as its database , and there is no native access to it, other then through AXL queries and queries via CLI. (Unless you are a Cisco TAC engineer, in which case a local hash value gets put into a hash value, which will the generate temporary root access). If db replication breaks,Continue reading “How to Check DB Replication status in CUCM?”

Restarting a server closes all the processes that are running and starts them again.  Restart of server is necessary for the system to reduce the failure that is due to long term running of servers/Services. Ensure that the restart happens at a time only when the server is being scheduled for maintenance. There are two ways to restartContinue reading “Restarting Call Manager”

There are logs in call Manager for each service running on it. The logs will be used to trace the cause for the issue, malfunction or abnormality in the server and its services. We have to be specific in the time frame of issue, so that we can collect the logs for the time frameContinue reading “Steps to collect Call Manager logs in RTMT”

The Network Time Protocol (NTP) is a protocol used to synchronize computer system clock automatically over a networks . The synchronization of time on computers and networks is often vitally important. A mechanism is required to disseminate accurate time around a network to computers and network devices in order to maintain order. For Cisco Servers, cisco recommends not to useContinue reading “To Check NTP synchronization status in Call Manager”
