VOIP sessions closed

[Strongiukas]

Hello,

We have a problem with VOIP. 

We are migrating from Cisco firewall to Checkpoint. On Cisco- everything works fine, but as soon as we switch to Checkpoint- VOIP stops working.

Tried to troubleshoot with VOIP provider and they gave info that session between phones and their server disconnects after 150sec. But session have to be 300sec.

I have created a new service on port 5060 (to avoid SIP ALG), then extended session time on that service to 300sec. But it didn't help.

We don't see any logs for dropping sessions.

Any ideas?

What version/JHF on what appliance?
Note we have a service (SIP_ANY, I believe) that can be used which doesn't use the ALG functionality.
What logs show up for the relevant traffic?

You may as well verify below sk, specially section 7, because I can tell you right now and Im willing to bet in 1000$ with anyone, FIRST thing TAC will give you if you open a support case is exactly the same article.
