[OpenSIPS-Users] B2BUA with challenge authentication

[Arnold Vriezekolk NETZOZEKER B.V.]

Hi,

I'm trying to play a soundfile before getting connected to an endpoint. The
initial invite comes from our sip provider which uses challenge
authentication.

The soundfile is played correctly, but when the B2B tries to re-invite the sip
provider the provider asks for authentication. This way the b2b fails and the
call will be disconnected (or remains forever without actually being connected
to anything).

Is b2b able to do the challenge authentication against the sip provider? Or
should i solve this in another way?

Pcap of the call: http://vriezekolk.org/~tuxx/31-05-b2b-soundfile.pcap

The number i'm calling from: 0575-568777
The number i'm calling to: 085-7600049
