pbxuser25 Posted December 22, 2015 Report Share Posted December 22, 2015 Hi all, I am experiencing very unusual problem from yesterday. When /two/ specific agents are calling, no matter internally or not, other side cannot hear the, at all. However, the agents hear the opposite side. It is only with with them /and it is not a microphone thing, as I can hear everything on the records/ It is more like a transport problem, but I cant resolve it. Anyone could help, please ? It is urgent. Thanks! Quote Link to comment Share on other sites More sharing options...

pbxuser25 Posted December 22, 2015 Author Report Share Posted December 22, 2015 Right now, one of the agents is connected directly to the provider /skipped the pbx/ and of course everything is fine, except the fact that that agent is not in the loop that, of course is not good / acceptable. The provided log is my case - my desktop phone /Yealink Tiptel IP 284/ which I used so far without problems. When I setup an x-lite client with same settings - everything works... so the problem it is not the settings I believe... Any help would be appreciated!Thanks !

pbxuser25 Posted December 22, 2015 Author Report Share Posted December 22, 2015 The problem is solved. What I did ? ... Well, since the server is using dual NIC, I decided to bind the IP address of the main one. Then I did a restart of the system /not the server/ and now everything is back to normal. Any ideas why was that ? I did some changes during the weekend, but if that was the problem, I think that all agents had to be affected because of that ? ...Anyway, it is something which might be helpful for someone in the future. Best, Tim Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted December 23, 2015 Report Share Posted December 23, 2015 Maybe the default route was the problem. I remember that in Windows, unless told otherwise, Windows picks the interface with the higher speed as the default interface. If they have the same speed, it might be random which one gets selected.
