We have Avaya IP Office 500 and Nortel BCM 50 and we want to connect them to each other using VOIP Trunking. On IP Office I can create H323 line with VoIP settings, Incoming Call Route (with right Line group ID) and short code for dial BCM 50 (is this ok, or I must do anything else?). What I must configure on Nortel BCM so I can dial extensions on IP Office and reverse. Any help is appreciated.
