Currently, i configure cucm 7.1. I have added route pattern 9.! point to E1 line. I wonder why call to certain celular provider is dropped, on the other hand call to international, local, long distance number, a few celular provider is working. I haven't configure any partition and CSS.
Is there anything i have to do with the numbering plan in route pattern 9.!? I installed the cucm in Indonesia.
