Sure, but why not do SIP between GW A and B?

really? i can do this?:

Phone(1607)------Nortel<------sip----->gwA<-----------SIP----------->gwB<------sip------>Broadsoft------Phone(26861168)

if it's possible , what are the changes in the configuration? can you show me with the script?

[Chris Deren]

Sure.

thanks Chris for you help, but i need realize to you another question, this diagram it originated because a problem with a integration between two PBX, Nortel and Broadsoft through sip trunk, the Nortel PBX forward the uri with the next format:

From: <1607>phone-context=SIP_cdp.SIP_udp@sip.nextel.nextel.cl;user=phone>

But the Broadsoft can´t recongnize the "phone-context=SIP_cdp.SIP_udp", because this we put in the middle a Asterisk PBX, like a bypass, but with the same results, the Asterisk can recognize the "phonecontext=SIP_cdp.SIP_udp" and the call can´t perform.

Nortel says we cannot modify the uri, and Broadsoft says the platform can´t reconize this uri, for all this is the solution with gateways, Chris think that can be done?
