Asterisk - CS1000

Asterisk Asterisk Support

Hi

I am trying to connect a Asterisk server to a cs1000, with SIP. It’s working, but not good enough yet.

The problem is, that i have to set “allowguest=yes” i asterisk in order for the incomming sipconnections from cs1000 to work. I do not know how to get this into a siptrunk and then put it into a context (except the default context oc).

I want the connection to go into this, in sip.conf:

[nortelincomming]
type=friend
host=192.168.0.11
qualify=yes
insecure=very
context=from-nortel

The link from the cs1000 is from a provider, so I do not have much to say about the cs1000 config (ok, a little bit.)

first SIP header for a call:

Offcourse, "sip:44793;phone-context=somethingcdp.somethingudp@something.com;user=phone" is the clue i guess, but i can’t seem to understand how anyway…

Can anyone please help me? :smile:
