[Freeswitch-users] call not connecting sometime

[David Ponzone]

Phiippe,

I analyzed the trace a little bit and some things are odd.
Between lines 570 and 650, your provider (webcalldirect) sends you back twice a 183/SDP, but the IP in each SDP is different.
First:
o=ppmt 1303657356 1303657356 IN IP4 62.41.83.72
and then:
o=ppmt 1303657357 1303657357 IN IP4 208.167.230.118

I am not really sure if it's valid to REINVITE during early-media.
Anyway it seems, you don't receive early-media.
To check that, you would need to take a full trace (with tcpdump or wireshark/tshark) to see if you receive RTP traffic from them after they sent you back the 183/SDPs.
If they don't, it's quite normal you don't have ringback.
That's ugly.
But then, the worst part is that you never receive from them a 180 Ringing (meaning that the remote endpoint is ringing or that someone in the middle pretends it is) or a 200 OK (meaning the call was answered).
Again, not surprising the call fails.

We could spend hours trying to fix their issues, but I think the quick way is for you to get a test account from another reliable provider.
The one you use does not have a strong reputation. If I am not mistaken, it's one of those services with 30 different domain names and websites slightly different, all selling the same "service" with "free" calls.
I recommend you first validate your config with a good one, and then you'll go hunting for the cheap one (and remember that generally, with retail providers, cheap price = cheap quality).
