Hi Edwin,

The called number 90566919592 is matching 7 pots dial-peers(1009-1016) which are pointing to different 7 different FXO ports. Now i guess your analog pstn line is single channel.If you need to test call on this PSTN connection , i would suggest below.

Create a new explicit pots dial-peer and point it to a port on which you have connected your analog PSTN line.

dial-peer voice xxxx pots

corlist outgoing domesticcalls

description "Calls to Mobile carrier - Saudi Arabia"

destination-pattern 90566919592

port 0/3/3

forward-digits 10

no sip-register

Thanks

Hi manish,

But the call was going through 0/1/0 where the pstn in connected right

[Manish Prasad]

So where is the problem ? Is you PSTN link works fine with port 0/1/0 ?

I was going through debug that you shared for called number 90566919592 which is matching destination-pattern 905[0-9]....... and that is not pointed to 0/1/0 port.

Thanks
