[cisco-voip] how to map DIDs to extensions during SRST

[Robert Kulagowski]

I guess I'm still not following then.  Are you trying to translate 
incoming digits (PSTN is sending 4, but you have 6-digit internal) or 
are you trying to do something else?

Is this a fax problem, or a IP phone issue?  Because for faxing, we have 
to hard-code the FXS ports with 6-digit destination-patterns.  IP phones 
just register with the router when they go into SRST mode.
