is it possible to configure a device as a trunk.
i have a gateway at ip address 1.2.3.4 connecting to a Nortel PBX with E1
i would like to connect Nortel’s extensions to an asterisk sitting at 11.22.33.44
Asterisk’s extensions would like to dial Nortel extension and vice versa.
Three possibilities to investigate:-
A add two PRI’s to the asterisk box and insert yourself between the PSTN and the Nortel
B add one PRI to asterisk and one to the Nortel and then arrange trunking and routing to suite.
C If your Nortel has SIP services licensed then maybe start with

hi
the asterisk is in the cloud, the gateway is connected to a PRI on the Nortel. i was looking at setting up a device and and have the gateway register to it.
Don’t know if i can change it to Dial(SIP/GATEWAY/${EXTEN} and route the calls over it
What is the nature of “the gateway” ?
it’s an adtran gateway
You should be fine, just build a sip trunk in Asterisk to connect to the gateway. You might want that trunk to have the [from-did-direct] context, and of course any pertinent provisioning in the adtran to accept connections from the Asterisk box.
i was looking for the gateway to register to the asterisk server and not asterisk to gateway is that possible ?
IP to IP trunks don’t need to register, no password or username needed either, they just work if you have correct firewall settings.
I was looking to avoid getting any changes made to the customers firewall
That is also out of my control but if SIP and any resultant RTP connections are passed without any modification then you should be fine.
thanks for your help
