Wasim, As I understand, mtp2 is hardwarely assisted sigchannel, which functionality is implemented in DIGIUM cards to act like dchan in PRI. I'd like just to confirm that we're speaking about the same, and if so SANGOMA must have such a support in their firmware too. As I know SANGOMA have hardware assistance in their card for the own SS7 solution, but will this work for Asterisk SS7 - is a question.
