External calls to voicemail dropping after about 40 seconds while leaving a message with SIP trunks 1

[waterwalkerLA]

System version: 11.5.1.14900-11

Hi everyone,

We are having trouble with external calls dropping while leaving a message in unity voicemail. We have tested with internal calls and it works correctly or as designed. We are using SIP trunking to a cube and have confirmed these settings are correct in regards to rtcp and timer rtcp. Any suggestions are appreciated.

Example -----------

router(config)#ip rtcp report interval 12000

router(config)#gateway

router(config-gateway)#timer receive-rtcp 5

This will allow 60 secs before the call will be cutoff. 12000 msec x 5 = 60000 msec / 1000 = 60 sec

router(config)#ip rtcp report interval 60000
router(config)#gateway
router(config-gateway)#timer receive-rtcp 5

This will allow 300 secs or 5 mins before the call will be cutoff. 60000 msec x 5 = 300000 msec / 1000 = 300 sec

Have you done a SIP debug to see what the message is when the call is dropped?

No I have not but I will do that next. I am kind of new to Cisco after 20 years with Avaya.....would this be through the real time monitoring tool?

 

[gnrslash4life]

You could grab the CUCM logs from there yes. Or i would probably start at running debug ccsip messages on the router itself just to see if anything sticks out. If nothing did, then i would grab logs from CUCM and Unity and go from there.

Thank you so much gnrlash4life.

 

[waterwalkerLA]

I just wanted to update you all, after running a debug it appears the our service provider is dropping the call after 60 seconds. We will now open a ticket with them and I will update this post when we get this resolved.

 

[waterwalkerLA]

After running the ccsip messages debug and confirming our ip rtcp settings.

router(config)#ip rtcp report interval 60000
router(config)#gateway
router(config-gateway)#timer receive-rtcp 5

I opened a ticket with our SIP vendor uploaded the debug traces to convince the vendor to look at their gateways. They adjusted what I believe are the rtcp settings on their end and now everything is working fine.

Thank you gnrslash4life
