Hi, just wondering is it possible to hook a nortel IP phone into a cisco call manager, or vice versa? or is cisco only compatible to itself, same with nortel? thanks

call manager is EXTREMELY proprietary (as with all cisco equipment)...if you've got the newest version of call manager you can use true SIP transport instead of just skinny or h.323...but this is more for PBX to PBX trunks and not for phone to PBX communication...but it's probably still going to balk at the phones...though cisco documentation does state the the new call manager can have sip phones

nortel is pretty tight on their controls as well..they're not big fans of playing nice with other people's equipments

for the phone end...cisco phones can communicate with any PBX that can use skinny...i've got a fonality PBXtra (based off of asterisk...it's the enterprise level of trixbox) and it can talk with cisco phones just fine because it's got skinny controls...from my research (sorry i don't have a nortel system on hand) nortel does not support skinny (SCCP)

a quick search seems to confirm this...all results are about using 323 or SIP trunks to communicate between nortel PBX and CCM...but squat about using a nortel phone with cisco equipment

thanks for the info, my boss handed me a nortel phone today and was like, make it work... i didn't think i could with my current version, but he insists it can happen. again, thanks for the clarification ^^

ah...if the boss asked...he's probably not going to take my word for it hehe

if you've got a smartnet sub on your CCM i'd give cisco a call for a definitive answer
