[Freeswitch-users] Outbound Audio Lost AFTER placing on Hold and picking back up.

[Sean Devoy]

Hi All,

I have a location that has been working solid for many months now, but the user reported a problem today.  I can extract the FS LOG if anyone thinks there could be valuable data there, but unless requested I don't want to try to "redact" them.  Also, this is a single occurrence problem so I am not ready to jump in the life rafts yet.  But, this community frequently amazes me with solutions so it is worth asking.

Here is what was reported to me:
Yesterday at @ 3:38 had 2 calls come in.  1st call was fine until a 2nd call came in. First caller was put in hold; 2nd caller taken care of, then returned to 1st call.  After 2nd caller disconnected 1st caller could hear Heidi but Heidi couldn't hear her then line disconnected. No. of that caller was 443-8xx-xxxx

I read that as:

1.   Call A answered.  2 way audio is fine.

2.   Call A placed on HOLD.

3.   Call B answered.  2 way audio is fine.

4.   Call B hangs up.

5.   Call A taken OFF HOLD.  OUTBOUND AUDIO ONLY.

6.   Call A disconnected????  (I am skeptical on this, how long do you sit on a NO AUDIO phone line before you hang up yourself.)

The configuration is:
FS on public IP <- ROUTER -> Internet  <-NAT ROUTER -> Cisco SPA504G.

I have no knowledge of the tech details of a line being placed on hold and then picked back up, so I hope you all have some ideas.  Anything special for NAT concerns here?  I do know that we have assigned each Line a separate port number of the SPA504G which helped with the initial setup.

Anthony - I got your book BUT - My wife wrapped it for me for XMAS - grrrrr.
