[asterisk-users] Orginate not working well with PSTN lines
Dear all,
I am from Saudi Arabiya and I am using digium hardware with asterisk 1.6.
When I am executing following AMI originate API. Orginate start to
execute extenstion without knowing of PSTN(FXO) channel is ringing.
Any one can help me to resolve this issue ?

"Originate successfully queued" only means that the originate action was handed off to asterisk not that is was executed yet. There are other events, depending on which events you are "reading", that tell you the call was answered and such. -- Jim Dickenson mailto:dickenson at cfmc.com CfMC http://www.cfmc.com/ On Apr 26, 2011, at 2:43 AM, Ashik Ali wrote:> Dear all, > > I am from Saudi Arabiya and I am using digium hardware with asterisk 1.6. > > When I am executing following AMI originate API.

Hello.
Considering the following setup:
Legacy PBX --(ISDN)--> Asterisk --(MFC/R2)--> PSTN
When a user dials out, Asterisk receive overlap digits, matches them to an
extension and dial the PSTN, completing the call. So far so good.
The issue I'm trying to solve (or at least improve) is the call takes much
longer to complete than the users were used to before having Asterisk between
the PBX and the PSTN. It happens because the digits are sent to the PSTN only
after the extension is matched in the dialplan, and dialing on MFC/R2 takes a
few seconds.
Here's the console log. Notice how it takes 6 seconds from the instant the
user starts dialing to the instant the dialed number starts to ring. First 3
seconds is the user manually dialing plus Asterisk absolute timeout. Next 3
seconds are the time Asterisk takes to dial the number to the PSTN and the call
be accepted.
[Apr 26 10:57:13] -- Accepting overlap call from '7416' to
'<unspecified>' on channel 0/1, span 2
[Apr 26 10:57:13] -- Starting simple switch on 'DAHDI/32-1'
*** User finished dialing + Asterisk absolute timeout ***
[Apr 26 10:57:16] -- Executing [0145333114657 at pbx:1]
Answer("DAHDI/33-1", "") in new stack
[Apr 26 10:57:16] -- Executing [0145333114657 at pbx:2]
Dial("DAHDI/33-1", "DAHDI/g1/0145333114657") in new stack
[Apr 26 10:57:16] -- Called g1/0145333114657
*** Asterisk starts dialing to the PSTN ***
[Apr 26 10:57:19] MFC/R2 call has been accepted on forward channel 1
[Apr 26 10:57:19] -- DAHDI/1-1 is ringing
*** Dialed number finally rings ***
So my question is: is there a way to fully overlap the digits from the
user's phone on the PBX (ISDN) to the PSTN (MFC/R2), eliminating the need to
wait for an extension to be matched? I already have overlapdial=yes in both
spans, but that didn't made it. Also googled for it, even searched this list
archives but found nothing.

Thanks for your solution. Anybody can explain me why asterisk is unable to detect ringback tone from PSTN telco ? . Does anybody successed; to make asterisk to detect ring back tone from PSTN telco ?

When dialing is finished on an analog FXO Asterisk considers it answered. The solution is to use something that is not an analog FXO like PRI or SIP to a carrier. -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Ashik Ali Sent: Wednesday, April 27, 2011 7:15 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Orginate not working well with PSTN lines Thanks for your solution.

The only thing the kernel modules could possibly do if the "ring" tone is detected is queue an event on the channel for Asterisk to decide how to handle. Asterisk / chan_dahdi is already typically monitoring the channel for DTMF digits and looking for additional tones and patterns could be added there. Asterisk would potentially need to have the tonezones of all possible destinations loaded which would make this complex and resource hungry.
