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!

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 !

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
