Hi,

I've searched the asterisk.org and voip-info wiki sites, but not found an 
answer that seems to match.

Hopefully this is a simple question. COLP is working very well on our 
system - Unfortunately it is working a bit TOO well in some circumstances. 
We have some "untrusted" trunks. On these trunks, an initial CallerID can 
be used, but any redirected caller numbers, COLP updates etc are not safe 
to accept. Sadly I cannot find how to cause COLP updates to be ignored for 
a trunk.

I need solutions for SIP, IAX and DAHDI, what options do I have? This 
applies to both in- and out-bound calls.

Are there some variables that I can set just before dialling an outbound 
call, and immediately on receiving an inbound call to determine what the 
callerID values will be for the entire duration of the call? (ie. 
old-style pre-COLP behaviour for specific trunks)

Thanks for any pointers.

Regards,
Steve



I believe what you are looking for in Dial is the 'I' option.
