FalconTech Posted August 22, 2014 Report Share Posted August 22, 2014 We have a strange issue where our customer is able to make some outbound calls without issue but other calls fail to even leave the PBX. The phone reports that the number is unavailable and we hear a fast busy signal. Why would most numbers work but others do not? Quote Link to comment Share on other sites More sharing options...
Vodia support Posted August 23, 2014 Report Share Posted August 23, 2014 I have seen this with some carriers, you can turn on the PCAP setting on the extension level. Follow the instructions below. http://wiki.snomone.com/index.php?title=Extension_PCAP Quote Link to comment Share on other sites More sharing options...
Lyle Chritton Posted September 16, 2014 Report Share Posted September 16, 2014 Turning PCAP on will get you the why it's happening, but not the quick fix. :-) We had similar problems as well with slow dial-outs and sometimes the following will help, but we, too, are *still* having this issue <sigh> which is, as Vodia Support pointed out, related to those damned carriers: 1st off: If you're in the US, always dial 1+area code + phone number. It never hurts, and sometimes works.. really!. 2nd: This may be DNS-related, and our 50% fix was to : Set "outbound via Proxy" and specify the FQDN and port for the VoIP server, e.g.: sip.domain.com:5060 Set in your topology (if you have it): - If using STUN or ICE, select "Discover public IP address (STUN)" and specify the FQDN and port of the STUN server address, e.g.: stun.stunserver.com:3478 -- if not using STUN/ICE, then just select "None (use local IP address)". Finally in your Transport section (if you have it): - Explicitly specify UDP as the Transport, or possibly TCP, but only if the server supports it. If you do find a fix, please post it.

Vodia PBX Posted September 17, 2014 Report Share Posted September 17, 2014 I would definitively check the logs. It could be that the trunk was temporarily not registered, or that the number of maximum calls per system/domain/extension has been reached. Those things would be visible in the log.
