We always assumed it couldn't be done, so for years we all struggled with SIP URI's.
So I did a GRIP request for it... Guess what? It's been possible since release 5!
Here's the response:
"This GRIP is declined as the following capability should address the requirement. IP Office 5.0+: If the wildcard * is used in the SIP trunk's Local URI, Contact and Display fields, that SIP trunk will accept any incoming SIP call. The incoming call routing is still performed by the system incoming call routes based on matching the values received with the call or the URI's incoming group setting. If outgoing calls are using this SIP URI, all valid short code CLI manipulations are used (transforming calling party number to isdn will be ignored)."
It actually works, with one "but": IPO will send "Anonymous" in the name field, although the number is correct. Our provider immediately responds to that and blocks the number.
ARS-entry:

Bottomline, you only need one URI, with the stars. Use it like and ISDN line.
