I have CCM - version 4.1(3)sr2.
Voice gateway -MGCP 2811 have connection to PBX Ericsson MD-110 via QSIG. This gateway included in Route List.
I have route pattern on CCM which must do called number transformation.
When I am doing test call I see on display of my IP phone that transformation happend, but ISDN debug on voice gateway show that called number didn't transformed.
