WARNING! Bug on Mitel ICP-3300..

(1/2) > >>

I really don't know guys if you haven tried this, but believe me ...

If you define a SIP trunk with ANY PBX (I mean, 3CX, Asterisk, even a Cisco router), you will can to call to ICP-3300 without troubles...

All this, without define a SIP trunk on the Mitel... you just have to define it on the PBX that you wanna make the call...

Have you even try this?

AH! I have tried it on Mitel 3300 Rls. 7.1...

Saludos!

Interesting.   This would explain something I'm was dealing with a week ago when a Nortel BCM could place calls to me but I couldn't bring the trunks up.

Thinking out loud here.....   What does this do for our security?   If there is an internet accessable 3300....   Sip client wouldn't work.    But... you could set up a SIP Server (i.e. Astrerik) and then run a SIP client off of that.   No inbound calls, but if COR security isn't set properly you could loose a fortune fast.   Better verify (1) no SIP access from internet.  (2) Your COR is correct to block outbound calls from this.

Yes, you're right. But if you are using IP Trunks, it's more complicated...

Actually I'm using "SIP Peer Profile Assignment by Incoming DID" form, It's a good way to block the undesired calls from undefined SIP trunks...

ralph:
Now I have to get a grasp on something new.
How does the "SIP Peer Profile Assignment by Incoming DID" block unwanted calls?
That's not a challange, I just don't know.

If all the form was empty would it stop incoming calls or do numbers have to be defined in the form to work?

sadzas:
