Hi,

First remove dialpeer 3 as it isn't needed. Then remove the command 'forward-digits all' from dialpeer 10.

After this make a test call from FreePBX and share the output of debug ccsip mess and debug isdn q931

Wilson Samuel · ‎09-15-2015

Just adding to Mohammed's point:

How are you dialing out from the FreePBX? I dont see any VoIP dial-peer to catch "all" for configured for the PSTN on the router, that could be the reason.

Secondly, please share the output from "debug voice dialpeer inout" while you are trying to dial out from the FreePBX. It will explain what is going on in terms of dial-peer.

Hi Wilson

Thaks for comments

Can you plese elaborate and text the commands

Vivek Batra · ‎10-30-2015

What Wilson meant to say is there may not be seen any VoIP dial peer matching for the calls from FreePBX to gateway, hence share the output of follwowing commands from gateway;

debug ccsip messages

debug voice ccapin inout

debug isdn q931

Dear Vivek,

I can't provide with the traces now bcz am not at my workplace now however i will manage it ASAP.

secondly I am confused with comments "What Wilson meant to say is there may not be seen any VoIP dial peer matching for the calls from FreePBX to gateway

If I am not wrong i think i have created the dialpeer for calls from FreePBX to gateway named as dial-peer 10

dial-peer voice 10 pots           //PRi pots outgoing
destination-pattern 9T    //my extensions inside use 9+ number to dial outside
port 0/1/0:15                 //use this port/pri for outgoing
forward-digits all

Plz PLz comment if this not the outgoing dial peer and plz provide me with exact code to call from pbx to gateway and then to pstn via PRI

Vivek Batra · ‎10-30-2015

Yes, you're right. This is outbound dial-peer to make outgoing calls through PSTN but you also need inbound dial-peer for calls from freepbx to gateway, something like below;

dial-peer voice 200 voip

incoming called-number .

session protocol sipv2

codec g711ulaw

Adding above dial peer should fix your issue. If not, I will be requiring the debugs output which I mentioned earlier.

Also let me know that you've configured forward-digits all command under dial-peer voice 10 pots, does service provider wants prefix (9)? Please crossverify and ignore my comment, if 9 is a part of original called number.
