TW is known to give grief for this exact issue.
Client should insist it worked before and that they should not blame the system.
Tell TW that they may need "TWTC hybrid SIP/T1 service package"
Raise hell and threaten to go back to the last carrier if need.

This stuff happens in Canada when people go with a Cable company for telephone service. You want cheap? pay the price!

I dont know if this will work but most people do F4 9 XXX-XXX-XXXX
They are always forwarding to the same bloody cell number so what I do is setup a Dest code for those whom need to do Ext Forward, it's less work to forward....just F4 8X (where 8X is the Dest code).

So in this example setup Dest Code 81 to use Route 001
In Route 001 tell it to Dial XXX-XXX-XXXX (persons cell #) and to use PRI-A.

So what we have here is the Route dialing the number and not the set.
Hopefully the call will be handled differently by the carrier since the route is calling the cell and not not the set and send out as the main calling number.
