Hi everyone,
I have two Mitel 686i phones which I added to my FreePBX install, using PJSIP. However, when I call each extension, its rings but no audio. Please any advise or pointers? This is a test system so no purchases have been made yet so Endpoint Manager is not available. I captured the traffic using Wireshark but can’t figure out what the issue is
Usually no audio means that signaling worked and media didn’t.
In SIP, signaling and media happen via different ports and are conveyed using different means.
Is there a nat or firewall between FreePBX and the phones? (that can also impact it).
I’d check the pcap to make sure that the rtp is getting to freepbx on both sides and make sure that the addresses in sdp are the correct ones for the phones depending on your network topology.
On premise or cloud based? Are the phones on the same network? Is your PJSIP setup as 5060 under sip settings?
In Asterisk SIP Settings, confirm that External Address and Local Networks are correctly set. If you change these, you must restart Asterisk.
Can you call *43 (echo test) from a Mitel? Do you hear the prompt? Hear the echo?
What happens on a call from a working extension to a Mitel? From a Mitel to a working extension?
Try uploading the .pcap or .pcapng file here and we’ll take a look. Either rename it to a .tgz or put it in a .tgz.
Thanks a lot Mathew, Jerremy & Stewart1.
It is on-premise and tomorrow, I will test the echo call.
Yes, it is setup under port 5060.
The softphone, MicroSIP to MicroSIP works perfectly; there is no NAT as all are within the same subnet; no firewall issues too. I will call the Mitel from the MicroSIP and capture the traffic too.
Unfortunately, I cannot upload but here are some UDP stream, I removed “at”.

In Asterisk SIP settings, External Address and Local Networks are not correctly set.
104.145.12.182 is the default address when the system is first installed.
From what you have posted so far, Local Networks should be 10.117.38.0 / 24 , but include other local networks if you have them.
After changing these settings, Submit, Apply Config, then restart Asterisk (fwconsole restart), or reboot the entire server.
It worked. Thanks a lot Stewart1, you are truly a FreePBX guru
