Strange Audio on incoming/outgoing calls


(Les) #1

It seems all of my trunks are ok except for one.

Everytime there is a call (incoming or outgoing) that uses a particular trunk, as soon as both parties have picked up the phone, the person not using the PBX hears a Latin music playing. Always the same song. I don’t have any such music in my on hold so I know its not coming from there. And I’m really at a loss of what could be the issue because everything was working about a week ago then it suddenly stopped. Running freepbx 15, asterisk 13 in a VM. I did move the VM from one host to another a little over a week ago. The problem started about a week ago. I don’t believe that should be the cause as I’ve restored a backup from 2 weeks ago and 2 months ago and both experince the same problem interestingly.

Here is the call log for an incoming call:

Any help would be appreciated.


#2

I strongly suspect that the trunking provider (or their upstream) is playing hold music when they do not receive proper audio from the PBX. The question is why has this suddenly started happening.

Some guesses:

FPL (FreePhoneLine ?) made a change so they are now fussier about codecs or packetization.

FPL changed media server addresses to ones now being blocked by your firewall.

Your router/firewall has a buggy SIP ALG and an otherwise innocuous change has caused it to malfunction.

Some debugging options:

  1. At the Asterisk command prompt, type
    sip set debug on
    and make another failing test call. Paste the Asterisk log (which will now include a SIP trace) at pastebin.freepbx.org and post the link here.
  2. If the above doesn’t show the problem, run a tcpdump capture on the PBX of a failing call and post it. This will show whether proper RTP is being sent to the correct address and port at FPL.
  3. If (2) also doesn’t show the trouble, capture traffic on the WAN interface of your router and check for proper RTP being sent to the right place.
  4. If (3) still shows no problem, you could try accessing the FPL account from another device or another account from this device.
  5. If still no luck, I see no choice other than getting help from FPL.

#3

at the cli type

rtp set debug on

it will reveal the ip of the media source
