CUPC through VPN

Unanswered Question
Sep 2nd, 2009


Were running CUPS with CUPC 7.0.

Over our VPN which goes through an ASA5510 V8.0(4) the client seems to have some difficulty updating the presence status.

The softphone seems to work fine but i cannot see anyones status and my status appears as offline. In "Server Health" it shows everything as connected and working.

On the network everything works fine.

I've been reading stuff about oversized SIP messages but Ican't seem to nail down the exact cause or fix for that matter.

Can anyone give me any advise??



I have this problem too.

Thanks Michael - we've turned off SIP inspection but no joy. I guess we'll have to upgrade!!

*** EDIT - Do you know what the bug is or the bug ID. I've been searching for it and can't see anything relating to my problem?

Are you using IP Address or Hostname during login screen of CUPC to connect?

Is the DNS servers same during VPN as within Enterprise? Try resolving the FQDN of Presence (for examples from the VPN.

Also add the IP address - Hostname entry in your Hosts file of the VPN pc.

It could be a DNS issue.

I am also facing the same issue with Check point VPN.

Did your problem got resolved ?

Please share how the problem got resolved ? is it a bug of Presence or its a VPN issue ?

the issue I was having was with a Cisco ASA.  It was a bug and also had to turn off SIP inspection.  I'm not sure about Checkpoint.
