Question : Asterisk SJ Phone Regsitration - '' is not a valid host

Hi All,

I have recently installed Asterisk on Gentoo and begun getting back into VOIP. Now I understand that a few things might have changed in the 12 months that I havent played with this but I have hit a snag thats driving me crazy. I have started by simply getting asterisk running and getting a couple of Softphones to register (SJPhone)

Real problem is that I cant get a single softphone to register.
in sip.conf I have:

[mysjphone]
 context=from-sip
 type=friend
 host=dynamic
 username=mysjphone
 secret=blablabla

and in Extensions.conf

 exten => 100,1,dial(SIP/mysjphone)
 exten => mysjphone,1,goto(100,1) ; To be able to dial with text, "mysjphone"

The error I am getting is [Aug 26 07:56:15] WARNING[19342]: chan_sip.c:12085 check_via: '' is not a valid host
and there is nothing that I can do to get past this - I simply cannot get any phones to register.

Anyone have any experience with this?

I'm not familiar with sjPhone... have you tried any other clients, like x-lite or zoiper ?
