Hi to all, I am having a difficulty in making outbound call specifically cellphone and National Direct Dial (NDD) calls. i am using Digium Wildcard TE110P T1/E1 Card and OpenVox A1200P/A800P ISDN card. My ISDN provider told me that i have to change my type of number setting from "national" to "unknown" to make the call. il try to find this configuration in system.conf, chan_dahdi.conf etc. but still i cant find where to change that setting. I hope someone could help me with my problem.
