[Freeswitch-users] error 403 registering at 1und1.de

[Christian Tausch]

Hi list,

i ran into a problem configuring the german voip-provider 1und1.de as a 
gateway. I have not completed my configuration yet, but in a first test 
the registration fails:

The response to the second REGISTER message is "403: Contact User und 
Anrufernummer verschieden" (en: 403 Authentication User Name does not 
match account name).

The visible difference between the REGISTER of freeswitch and the 
(working) SIP-client twinkle is indeed the user-string in the 
contact-header.

Freeswitch: (gw + name)
Contact: <sip:gw+1und1.de@<public-ip>:5080;transport=udp;gw=1und1.de>

Twinkle: (extension / login-user)
Contact: <sip:4921XXXXXXXXX@<public-ip>;transport=udp>;expires=3600

If this is the cause of the error message, is this expected behavior of 
a provider? And more important is it possible to configure freeswitch to 
set a specific contact-user?

Thank you for your time.

Christian Tausch
