[Asterisk-Users] Struggling with grandstream sip to asterisk

[marrandy]

Hello.

I had grandstream working fine to FWD through my firewall.

Now I want it to talk to the asterisk server.

Did lots of reading, attempts but I keep getting registration errors even 
though I can call to/from the sip phone from an analog phone on a tdm400 
card.

Basically.

grandstream = 192.168.1.70
asterisk = 192.168.1.1

The error I see is ;-

    -- Executing Dial("Zap/2-1", "SIP/206|20") in new stack
    -- Called 206
    -- SIP/206-582e is ringing
NOTICE[81926]: File chan_sip.c, Line 5215 (handle_request): Registration from 
'<sip:206 at 192.168.1.1>' failed for '192.168.1.70'

Can anyone give me a hint/clue about what is going on.

A good sip.conf for grandstream with a static address would help.

Regards...Martin
