SIP to PA System gateway just stopped audio.
-
I have two locations with PA Systems. Identical setups. One of them just stopped passing audio.
Here's the setup at both locations.
Cloud Hosted VitalPBX (Same PBX services both locations.)
Comcast ISP with static IP Address
Sonicwall TZ 400
Fanvil PA2S SIP Gateway
PA SystemBoth locations have been working fine for more than a month (Since install date).
Suddenly one location stops passing audio.No known changes to our equipment or software.
I've double checked all settings (comparing the non working site to the working site.) I've exported the setting from the working site and imported them into the non working site. And I've rebooted the cable mode and firewall.
No Joy.
Any ides?

I wonder if you have a NAT issue. Sonicwalls love SIP.

Did you reboot the Fanvil? Just sayin'...

Not passing audio tells us little.
Is the device registered?If it is registered, pop
sngrepon the command line and make a phone call to it.Look at what ports it is trying to set up for the audio channel.

No OS access. I'll have to get NTG involved. Standby......

Obviously, this will be the result of a specific call, and RTP ports are randomly negotiated, but it will tell you what that call tried to do. So you can then look at your NAT and Firewall settings and see if something is weird.

Yes. You obviously, cropped the IP info, but using that, look and make sure both side have the right things allowed. Assuming the PBX is hosted, then the side with your firewall is the one to validate.

I contacted the support staff at the host. I have to say, it never ceases to amaze me how good they are with this stuff.
They changed the NAT setting for the extension. I had no idea the setting was available because I have never setup a SIP device in VitalPBX before, only PJSIP. The NAT setting in question is not there for PJSIP.
This is the new setting on the Extension page for this extension:
I still don't know why it worked fine for a month and then suddenly stopped. I'll look in to that.

Don't do this. In Asterisk land (what VitalPBX uses) SIP (meaning anything using the
chan_sipdriver) is dead.chan_pjsipis still SIP, just a different driver on the server. It has zero to do with anything not on the server.If the device or provider accept the SIP protocol (aka everything does if it is not Cisco), then server side, you can use
chan_pjsip. -
