Bridge: Authentification error - but internal calls are possible

[Steffen Maier]

Hello,

I do have an old Panasonic PBX (TDE200) as a bridge salve, so I can still use the DECT solution they provided.
Calls get thru from 3cx to Panasonic, also vice versa, from Panasonic to 3cx - but only, when its an internal ext from 3cx.
On external calls (Panasonic > 3cx > Sip Trunk) I do get an "authentification error", what I don't understand - if the password would be wrong, then I should not even be able to call an internal ext. of 3cx.

Does anyone have a clue?

Thanks
Steffen

Are you sure that auth error is provided from 3cx? Maybe that error is coming from voip provider, some misconfiguration when bridge call is forward from 3cx to external destination.
Did you check activity log in 3cx for that kind of call?

There cannot be an error in the connection between 3cx and panasonic, as internal calls get thru.
Also not a problem with the sip provider trunk as this calls get thru - so why is it when I combine them.

This is what the log says: (makes no sense to me, as internal calls work fine)
