it takes a long time before the ring starts at outgoing call

[coertvc]

Hi all,

3CX v12, Cisco 525 and Yealink t22, server 2008 on VM, Firewall open from and to the Voip provider on all channels. 3CX only servers the internal 200.9 network. no STUN validation as I state my external IP

The issue;
when I pick up the horn of the phone and dail my cell, (as an example) it takes 8 seconds before by I get a ring signal and two seconds later my cell phone starts to ring. (i changed the inter digit time to 2 already)

27-feb-2014 12:30:53.746 [CM503008]: Call(C:17): Call is terminated

any thought why the call to start is taking so long, and in what way I can shorten it.

suggestions are very much appreciated

regards,

Coert

Re: it takes a long time before the ring starts at outgoing

On the surface it appears as though the 8 second delay is lost between the time 3CX sends and your provider responds.

27-feb-2014 12:30:52.085 [CM505003]: Provider:[12Connect] Device info: Device Not Identified: User Agent not matched; Capabilities:[reinvite, replaces, able-no-sdp, recvonly] UserAgent: [12Connect VPBX] PBX contact: [sip:999xx@[myexternalIP]:5060]
27-feb-2014 12:30:44.039 [CM503025]: Call(C:17): Calling T:Line:10000>>[outgoingnumber]@[Dev:sip:[email protected]:5060] for L:17.1[Extn]

You need to look at the verbose logs or get a wireshark as the log settings currently in use do not show the background negotiations taking place. It could be that additional authentication was taking place or maybe something occurring with codec and port negotiation. I am inclined to think that the issue is more than likely with the provider given that the 3CX system was able to process the call out to the provider in less than a second.

You might try calling a land-line phone or two and compare time delays. It could be a normal delay while the provider is busy handling his end of the call to ensure connectivity though the various networks to get to the desired endpoint and perhaps some simply take longer than others. There are a number of other things it could be, but a verbose log may give more insight.

Re: it takes a long time before the ring starts at outgoing

Have you confirmed that this delay occurs when calling a landline? I often find that calls to mobiles usually come with a much longer delay before ringing even starts, although the delay that you are experiencing is a bit excessive.
