Hello,

I am using a SIP account from Netvoip CH. I try to receive inbound call
from this SIP trunk. I discovered that, when they sent an invite, the
IP-Adress of the to: is their own IP address.
There fore ACL doesn't work and FS asks for authorization, which then fails

I receive the following message on the CLI:
2009-04-02 21:48:20 [WARNING] sofia_reg.c:1661 sofia_reg_parse_auth()
Can't find user [anonymous@62.65.128.62]
You must define a domain called '62.65.128.62' in your directory and add
a user with the id="anonymous" attribute
and you must configure your device to use the proper domain in it's
authentication credentials.

I could do that, but this is not clean and I do not have a password for
that.

How can I workaround this, so that Freeswitch accepts this call? Aliases
do not seem to work.

Here is a sample message after FS asks for authorization:
xx.xx.xxx.xxx is the IP of our Freeswitch
62.65.128.62 is the IP of Netvoip CH

I would expect
To: <sip:0715aaaaaa@xx.xx.xxx.xxx>.
instead of
To: <sip:0715aaaaaa@62.65.128.62>.
