Issue SIP over VPN (using CUPC call disconnect after 50 sec)

Unanswered Question
Jun 12th, 2009

Hi,

I am using personal communicator over VPN to make outside call, but VPN is working fine, but my call to Internal/external numbers go upto 1 minute and then die.

we use ASA 5510 with 8.0(3) IOS. We use NAT and I have noticed the below------

"timeout sip 0:30:00 sip_media 0:02:00 sip-invite 0:03:00 sip-disconnect 0:02:00"

Can you help me regarding the above issue, either to remove or reduce the timeout of SIP, as CUPC use SIP as a communication protocol.

Any help will be appreciated.

Thanks

I have this problem too.

As a call is set up, the SIP session is considered in the transient state. This state remains until a Response message is received which indicates the RTP media address and port on which the destination endpoint listens. If there is a failure to receive the response messages within one minute, the signaling connection is torn down.
