Sangoma B600D on Snom One outgoing calls always busy

Recommended Posts

Hello All

I have a System running good for a while, but recently seems so weird, My setup is a Sangoma B600D with Snom One Unlimited and for some reason can receive calls, but can not make outoging calls it always sound busy,internal calls between extensions works fine in both ways.

 

Any ideas what might be causing this, or where to look for clues?

 

Thanks.

 

This is my log

Check if the user has "Block outgoing caller-ID" set on the extension level.

 

The thing that I noticed in my system is that the snom one can not "communicate" with the sangoma card, for this reason the outbound calls can not be made. I can receive calls, but can not make calls.

 

Any other idea?

 

Thanks

Check the private indication on the trunk level and set it to remote-party ID and all the available setting.

The Custom header would work as well but you need to know what the provider would like to see in the from field otherwise they will reject it.
