Most likely, nortel is not able to reach cisco phones.

Hi,

Do u mean to say the return traffic from nortel to cisco???

But all the SIP ports are opened and prerequisites have been checked.

If it had been done properly, it would be working.

Recommend you engage a reputable consultant or certified cisco partner.
