Hi friends,

Here I am posting my problem. I am getting this problem since 8 days. I have studied documentation and looked previous posts in forums. But, I am unable to solve this problem. Please show me a solution. I am from Andhrapradesh, India.

We have installed Asterisk with Digium 04B card (4 FXO ports). Now, I have connected my PSTN (BSNL) line directly to first port. I am making outgoing calls and receiving incoming calls successfully through my Asterisk. The problem is: When I am receiving a call from outside (PSTN-Eg. Mobile), I am not getting the callerid number of the caller and getting callerid as “Asterisk” in my softphones (XLite).

From Internet, I came to know that

1. In India, we have to give dtmf and ring for cidsignallling and cidstart respectively.
2. Default Asterisk setup doesn’t recognise callerid in India. To recognize callerid in India, we have to do or change some modifications in chan\_zap.c source file. Is it right?

Here I am giving my config files and error message. Please see it.

When somebody calls from outside (Eg: mobile), I am getting this below error message on Asterisk console:
