How to have Input A Type Number (ANT) for SS7 in Asterisk to

Hi there,

Can anyone tell me where do I need to put the ANT (A Type Number) so that the calls sent from termination to the SS7 trunk of the Telco can be treated as “International Specific Numebr” for the CLI. We are We are using chan_ss7 to interconnect with a telco. At present the CLI we are sending with the international code eg: 1-416-848-XXXX but the telco is getting National Specific Number for the CLI. (Telco is in Asia and they require International Specific Number to pass the CLI)

Please help me find the solution.
