That's it !

Thinking it was going to make things easier to diagnose, I had chosen to
set the phones with a static IP. Apparently, wether defaultip is set or
not, when the phone uses a static IP address, some assumptions are made
about authentication. I do not understand what they are and which side
assumes something, but it prevents SIP registration. Setting
host=dynamic even though I use static IP addresses solved the problem.

Many hours went into finding that out. If somebody has a clue about how
the a static IP address influences the SIP registration process, I would
be happy to know about it.

I also saw it in several examples.

Thanks for all that advice, and thanks to others who contributed to this
thread. Now that I have completed my first Grandstream to Grandstream
call via the Asterisk server I feel much better and I can't wait for the
QuadBRI to arrive so I can really begin to make useful stuff !

Here is my current working configuration :

- In sip.conf :

[6040]
username=6040
secret=mysecret
host=dynamic
type=friend
canreinvite=no
dtmfmode=info
disallow=all
allow=ulaw
allow=alaw


- On the phone side :

SIP User ID: 6040
Authenticate ID: 6040
Authenticate Password: mysecret
SIP User ID is phone number: Yes
(everything else is default)


Nothing special about that configuration, so I guess it's not worthy of
a wiki addition. What would be and should really should be looked into
is the failure of SIP registration when a static IP is set without
"host=dynamic".
