[Asterisk-Users] SIP & Adtech 150

[Corrado Ventura]

Hi all,

Anybody know how to configure Asterisk (sip.conf and extension.conf) to
work with an Adtech Tipcome SIP Phone s-150?

Using a conf like this:

exten => 100,1,Dial,SIP/100 at adtech (in extension.conf)

and 

[adtech]
type=friend
username=123
secret=123
host=dynamic
defaultip=192.168.0.10

(in sip.conf)

I have "Registering Error!" on display and
NOTICE[5126]: File chan_sip.c, Line 3600 (handle_request): Registration
from '<sip:100 at 192.168.0.1:5060>' failed for '192.168.0.10' on *.

Thanks
