Is anyone using the VOIP helper?

Hi

I have not had any success in configuring the VOIP helper. I had it working in 9.1. But after upgrading, I had to use NAT rules for SIP and RTVP traffic.

My current set up is like this
SIP server networks: I put my phone trunk IPs.
SIP client networks: I put my PBX IP, also my phone network.

With just this set up, I will sometimes have no ability to connect, or the phone connects, but voice traffic is blocked.

are additional NAT rules needed for SIP or RTVP ports, or does the helper remove the need for separate NAT rules?
Whats the proper way to configure the firewall for a SIP PBX to an external truck?

Thanks

Never worked for me. I don't use it anymore because it makes much more trouble then it helps. You better put them in a separate VLAN (what you should do anyway).
