No audio SIP call

[calazans23]

I'm using a public IP address on the LAN interface 2 to record remote sip extensions. The record works, but the call does not have audio. When the call is waiting is possible to listen to music on hold. I checked the doors of RTP and softphone SIP devices, but is possibly sculpt audio on calls. Anyone know the solution to this problem?

Doors IP Office
RTP: 49000 ~ 53246

Doors sip softphone and handset.
RTP: 49000 ~ 53246

Already have disabled the firewall and checked the codec: G.711 A in Ip Offce and SIP extension

Sounds more like you have a one way speech-issue.

The usual suspect is SIP ALG / Inspection.

What kind of firewall/router do you have?

Kind regards

In further tests it is possible to have audio for incoming calls to SIP softphone but unable to hear audio when the sip extension makes a call through the PRI trunk.
