[asterisk-users] Connecting Asterisk to Nortel Succession 4.0 sip...

[Eugen Soare]

Well I am entering into a realm that I don't know.


3 sites with Asterisk
1 site with Nortel


Asterisk/Sip calls working fine between the 3 sites.

Asterisk to Nortel set calls working fine.  (call comes from asterisk to 
nortel and rings telephone, people answer and talk happens, hangup call 
clears)

Nortel to Asterisk. Set on Nortel gets a busy signal.

Any suggestions on what to look for?

Much appreciated!

Eugen
