[asterisk-users] Asterisk Trunk Name Problem

[Ondrej P.]

Hey guys.
I have a little problem. My provider requires me to make the trunk name 
of my SIP connection "i2telecom.com" (otherwise it won't register). 
Unfortunately, this name also becomes the identifier for the connection. 
Now, when I want to dial through it Asterisk think I am trying to dial 
through the domain "i2telecom.com" and not the actual connection.
I tried both, Dial(SIP/i2telecom.com/5551234) and 
Dial(SIP/5551234 at i2telecom.com). But neither one works.

Is there anything I can do?

Thanks,
Andrew
