Thanks for looking into it David!

I totally agree with you cheap rarely mean quality but sometime it has to do :(

Next time it happens again I will take a wireshark trace

As far as fixing their issue I doubt it will help. They tend to royally ignore you in case of problem

I only stick with them because in most cases (ie 98%) it works

I just wanted to make sure that the issue was not on FS side. If it is not then I am not going to pursue it!

I guess I will be on the hunt for another cheap provider (if anyone knows one ! )

Thanks a gain

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).

Hello,

I had the problem a few weeks ago but after a reinstall (unrelated to that) the problem had gone so I put it
done as my messing up my system at the time!

But today I had the same issue again. When I call sometime the call is not going through completely

The symptom on my side are that nothing happens (no ring tone) on the other they say that the phones
rings but when they pick up the phone they can't hear anything.

Below is a siptrace where I changed the number and IP so I hope I didn't mess it up too much.

Can someone let me know if they see something wrong? I tried to understand but it is beyond me :(

Regards
