Calls drop at 2 hours duration

ripcisco · ‎07-28-2010

I have a customer on a UC540 running latest code. They hold lengthy conference calls and complain that the calls drop at 2 hours duration (exactly 2 hours). I'm sure this must be an rtp timer tweak but can't find any reference. Any ideas ?

Thanks in advance.

What type of trunks are you using on this system?

ripcisco · ‎07-28-2010

SIP only

Hello Mr. Paul,

can you please show us the

show run

And

debug ccsip messages
debug voip rtp session named

when a non desire disconnection occurs?

it would be great if you can send this debugs to a syslog server for latter analisis

http://www.cisco.com/en/US/docs/security/pix/pix63/system/message/pixemint.html#wp1020115

sending it to the router console can significantly increase the router CPU

also something that comes into my mind, is the firewall configuration, if you can disable CBAC just to see if it is the firewall who is blocking the call?

or do you have another firewall upstream?

Thank you

Victor

Hi Victor, you're supposed to be on vacation ?!

I'll get some logs set up & forward to you in Cisco support. I'll post a resolution to the thread when we get one.

Thanks

Paul.
