Hi Joshua. Thanks for your reply. I will try to be more clear.

Imagine this environment:

Extensions(2222,2223,2224,...) ---- Asterisk ---- Nortel MCS ---- PSTN

I have a sip channel configured in Asterisk with Nortel. I received just one user/passswd to register Asterisk on Nortel. This user is a real phone number(30302221) that can be reached from PSTN. With just one number/user I have no problem to route a PSTN call to the correspondent Asterisk extension.

The problem occur when Nortel is configured to have some alias(other phone numbers) with the same user/password, that I told before.

30302222 -+
30302223 -|
30302224 -|---user:30302221 passwd:secret
30302225 -|
30302226 -+

Just 30302221 is registered by Asterisk on Nortel. If I call one of this numbers I will reach Asterisk, so I want to configure a DID for each one of them to ring an especific extension:

Phone #      Extension #
30302222 ->  2222
30302223 ->  2223
30302224 ->  2224
30302225 ->  2225
30302226 ->  2226

P.S.: I received on Asterisk an INVITE with the phone number called.

Could someone help me!?

Can Asterisk handle this!?

Thanks.

Denis Galvão.

You're actually confusing me when you say this due to the fact you're not giving much information, probably why nobody has responded yet. If the SIP server on the Nortel does an INVITE for the phone number, then asterisk will act accordingly and go to the phone number in the context you set for it.
Note that if the Nortel is incapable of handling a challenge for
credentials, you'll have to use a peer entry with insecure=very to match
based on it's host/IP address.

Hi all.

I need to implement the DID funcionality in a SIP channel with an ITSP. Is
this possible to get it working!?

The ITSP that im using has the "alias" feature in its SIP server(Nortel
MCS5200), they provide just one register user/password and below this user
they put a lot of other phone numbers.

Ex.:
register => 30302222
alias => 30302223
alias => 30302224
etc...

Any clue for it!?

Denis.
