[asterisk-users] How to dial extensions asynchronous-sequentially ?

Thu Jul 16 07:10:39 CDT 2015

Hi Pete.

No problem!

Maybe I will use only OpenSIPS, because it may be enough for me. But I still have to investigate some points.

As I was learning the past few days, due to the fact that Asterisk is not a SIP Proxy, it might cause some more difficult  in my project.

Best regards.

Heya Rodrigo

My apologies for the misunderstanding re the delay.

I think the 183 messages problem stems from Asterisk being a B2BUA not a proxy and therefore not the tool or this job. But others have more skill around that area than I do so please confirm that before accepting it as fact!

Hope you get it resolved. Sorry to muddy the waters :)

Hi Sammy and Pete.

Sammy, you are correct. But your example doesn't allow Asterisk forward every SIP 183 message to the caller.

Pete, in fact, I'm not looking for a delayed ring. All extensions must ring at same time. I got  a kind of solution by using:

exten = _6XXX,1,Dial(${PJSIP_DIAL_CONTACTS(${EXTEN})}, 60)

However, the Asterisk is rewriting the SDP content of SIP 183 messages, before forwarding it to the caller. That is the new question I would like to solve, because in my project the caller must receive the SIP 183 from callee as it was originally wrote.

Thanks and regards.

Heya Rodrigo

Not sure, but this expansion on Sammy's concept may help you achieve the delayed ring on the secondary extensions you were looking for.

exten => _600.,1,Dial(PJSIP/${EXTEN})
exten => _600.,n,Hangup

exten => _600.wait5,1,Wait(5)
exten => _600.wait5,n,Dial(PJSIP/${EXTEN:0:4})
exten => _600.wait5,n,Hangup

exten => 555,1,Dial(LOCAL/6001&LOCAL/6002.wait5)
exten => 555,n,Hangup

So you dial '555' and it rings 6001, then 5 second later (assuming 6001 isn't answered yet) 6002 starts ringing too (first to answer gets it).

Anyway here's one way of how I think you can do.

Have a context created to dial the individual user

[dial_user]
exten => _600X.,1,Dial(PJSIP/${EXTEN})
...

and in your code change it to.

same = n,Dial(local/6001 at dial_user/n&local/6002 at dial_user/n)
same = n,Hangup()
