VOIP traffic dropped
-
@timlie, the state gets created when the first packet is sent, if the firewall allows it. and the firewall rules that you've shared earlier seem to indicate that everything open on the subnet, so RTP should be passing.
At this point everything is pointing to a routing problem on the PBX's second interface.
Here is one way to troubleshoot that:
On the pfSense that is working with PBX#1, if you run the following from the command prompt:
tcpdump -s 0 -n -i lan_interface host PBX#1_IP#1 or host PBX#1_IP#2 or host PBX#2_IP#1 or host PBX#2_IP#2
you should see communications taking place, including RTP if any.
You can optionally add -w filename.cap to the tcpdump command to write it to a file, and then open it up in wireshark.If you see RTP traffic, then run the same command on the pfSense that is working with PBX#2 and check that the RTP traffic that PBX#1 is sending is going to PBX#2.

Thanks awebster,
This capture showed us that the second interface was still using our old gateway because of an ARP table which this pbx didn't refresh.
Fixed now!
Thanks a lot! -
Glad that was easy to fix.
