Re: ISDN PRI incoming calls problem

Your DP 1 is not matching the called number:

dial-peer voice 1 pots

incoming called-number 1..

Change to what you see in "debug isdn q931" and the call will accepted.

I don't know if you have DID and if so what "dialplan-pattern" is needed under telephony-service. That is also needed to ring the extensions directly from outside.

So configure incoming called-number 8020...

You can remove the port from the incoming DP, it is not used.

and "dialplan-pattern 1 8020... extension-length 3"

Then just use .. for incoming called-number in the DP that has direct-inward-dial. Or take debugs isdn q931 with term mon and place the correct number.

ok i ll try this tomorrow and reply abt the result

Re: ISDN PRI incoming calls problem

Hi,

put the cmd "direct-inward-dial" under your POTS dial peers this should stop the secondary dial tone, also how many digits is your service provider presenting BT present 6 by default so unless you have asked for only 3 to be presented you will need a translation pattern to change the incoming 6 digits to 3.

I hope this helps

Re: ISDN PRI incoming calls problem

The command under telephony-service is:

dialplan-pattern 1 8020... extension-len 3

This assumes telco is sending 7 digits for called number thing that you can verify with "term mon" and "debug isdn q931".
