[asterisk-users] Nortel Option 11C and SIP gateway integration

[Anthony Rodgers]

Hi Heison,

We got our 11C working using a direct PRI connection to a Digium card  
in our Asterisk server. We ended up having to use two PRIs to get  
CallerID working properly: calls to the Nortel from Asterisk are on a  
5ESS call-by-call trunk, which effectively has the Nortel treat the  
Asterisk server like a CO; calls to Asterisk from the Nortel are on  
an NI2 tie-trunk to allow the Nortel to send CallerID to the Asterisk  
server.

Hope this helps - I have the Nortel config we used in a PDF if you  
need it.

Regards,
