ICR and multiple accounts

[ipohead]

I have a series of numbers each with separate accounts from same provider which need to go to separate destinations - but all calls go to the first ICR based on their IP address.

I did try called number on the ICR but I note that all my numbers are followed by the same letters so the default right to left matching will not work. Should I just switch to left-right matching?

I see there are other options in SIP Line - SIP advanced or SIP line calls details so are these relevant?

In SIP trunk settings there is something like call number match (don't know it out of my brain) where you can set it to 'To header user part'.
