All, newbie to Asterisk and just trying to get a load of bits together including PSTN interface using Digium Quad E1 interfaces using EuroISDN. Question can I/how do I get access to the ISDN reason codes for call disconnect? The purpose is to be able to make routing choices based on the reason code returned from a PRI connected interface/channel. For example if the reason code indicates say "network congestion" or "no route" then I want to be able to try an alternative route by manipulating the digit string and retrying on another interface, for example to a SIP ITSP. Here's the scenario - call originates on IP cloud from an IP Phone/IAD/ATA connected via a proxy server (SER), destination PSTN via Asterisk, First choice route is out of an ISDN PRI port on the Digium board, if this route is either congested - no channels left to dial out on or the far end network has a problem such as can't route to that destination, Then take a second, third etc choice of route to that destination say via a SIP connection to another ITSP, or another PRI Interface connected to another PSTN provider. Any suggestions, thoughts, configuration examples and general advice welcome! Neill............;o) -------------- next part -------------- An HTML attachment was scrubbed...

Yes it works. It will go to priority 2 if the call was NOT ANSWERED for any reason (busy, number not in service, etc). You may need to add ,,g on the Dial line to get Asterisk to go to priority two if the CALLEE hangs up. I do not do post call processing if the CALLER hangs up. joachim wrote:> > > Are you sure this works ? (and does it work whatever end hung up ?) > > If it works, its not expected behaviour.

Did someone actually got this to work ? The examples on voip-info are not correct i think. It will never go to priority 2, since the call already got hungup at that point, using dial|g doesnt seem to work either.

Thnx Eric, Could you also post your extensions.conf ? (or just the extension calling that macro ?)

Are you sure this works ? (and does it work whatever end hung up ?) If it works, its not expected behaviour. (at least i dont think it is, it should never go to the next priority when the call got hungup). zoa.

Aha, oke :) I was thinking of the answered statuses. That g was not working for me last time i checked. But so at least its working when a call did not get answered, thats already good news for me.
