CTS System - Basic MultiPoint call analysis

The following information will help you how to perform a basic call control analysis for a Telepresence call between 3 CTS Endpoints and CTMS in this call we have 1 CTS 3200, 1CTS 3000 and 1 CTS-1300 system.

Versions:

CUCM 7.1.3.32900-4 Pub and Sub

CTS 1.6.5

CTS 3200 and CTS 3000 use ts4.local (Presentation codec).

Call from 3001,3002 and 3003 to 4006 around 15:45 PST time

Get the files from this location and look for the word: ##DEBUG##

+++++DEBUG+++++

You will find details in CUCM SDI, SDL, CTMS and CTS traces (CCA, CMR, OSD and TSPS) for each call

What to check?

Use CTS SYSOP logs

Check CCA logs

Check SIP logs

Check CUCM traces

Check CMA

Check CMR

If Security is configured check:

  - SECD

  - KEYEXCHANGE

  - SRTP

Check CUCM Configuration/Infraestructure (i.e. BEA, SBCs, etc)

Check CUCM Traces SDI/SDL traces

Use CTMS_SYSOP

Check SIP.LOGx

Check CCS

Check SWITCHING

Check RTP

Check ALARM

If Security is configured check:

  - KEYEXCHANGE

 

Troubleshooting

•Verify TelePresence SW Compatibility matrix

•From CTS CLI, verify Calling Services are up

•Verify System status in CTS GUI

•Verify system is registered

•Verify Region Bandwidth in CUCM (Check Video and Audio BW)

•Verify Location

•Verify CSS (Calling Search Space (Use Dial Number Analyzer)

•Check Route Patterns

•Verify SIP Trunk Security Profile matches what is configured in CTMS (Protocol, port)

•Check Region between SIP trunk for CTMS and Endpoints

•Verify Static/Scheduled or Ad-hoc meeting is configured in CTMS

•Check packet flow

•Use sniffer capture (Span port is recommended)
