I've installed a TDM400. Having a go with AMP.

I would like incoming calls to be put throuhg to an

extension (at my


desk) and a mobile (cell phone) at the same time. Whichever

picks up,


gets the call..

This should be possible with AMP (call groups,

200|201|0*0408xxxxxx),


but it didn't work, so I have created a custom-incoming in extensions-custom.conf

What is happening is, The extension rings for about 5 secs

(as long as


it takes the TDM400 to dial the mobile number), then just

the telstra


mobile rings..


From asterisk -vvvvvvvvvvvr

-- Goto (custom-incoming,s,1)
-- Executing Dial("SIP/202-b424", "Zap/g0/0408xxxxxx&Sip/200|30|t") in new stack
-- Called g0/0408xxxxxx
-- Called 200
-- SIP/200-fece is ringing
-- SIP/200-fece is ringing
-- SIP/200-fece is ringing
-- SIP/200-fece is ringing
-- Zap/2-1 answered SIP/202-b424


This tend to indicate to me that the mobile system has

picked up the


call request on the zap channel and that * therefore thinks

that the


zap channel has picked up the call and will then bridge the zap channel to the sip 202 channel and kill off the ringing on

the sip 200 channel.

I don't know that there is much you can do about this as

basically you


are trying to get interaction on two different systems.

No. Analog ports are always considered "ANSWERED" as soon as Asterisk finishes dialing. This is covered over and over and over again in the mailing list archives. There are a few very ugly hacks to work around the problem.




Thanks Howard and Eric,

I did have a look around for this before I posted and I found a few
references to:
callprogress=yes   (in zapata.conf)

But also read that this only (kinda) works in the US.

Also had a brief look at BackgroundDetect, but it looks a bit rough



What I do need to do urgently however is get rid of the 5 or so seconds of
silence and static noise between the time Zap says the call is answered and
Telstra establishes the call and starts ringing again..

So what I'm thinking is perhaps:-

- Call the phones in the office
- Call the mobiles seperately but at the same time
- wait for a DMTF tone from the mobile (I think I could put up with that)
- bridges the call to the mobile
- But if a Sip phone answers the call first hangup on the mobile
- bridges the call to the Sip phone

Any thoughts on how I would go about that?

You can replace the "t" option with "tr" at the end of your Dial line. However, if the destination is busy then you may hear a couple of rings and then a busy sound.


Why are you using "t" in the first place?

You really do need a PRI or VoIP service provider. These things are not really issues with PRI or VoIP.
