What that would imply is that Asterisk could be bridged (with configuration, not code) to an external voice mail system- most of the focus here is using Asterisk as a voicemail system for other PBX's. While Asterisk does have a way to indicate voicemail to a given phone (I haven't tried an h.323 phone, but it definitely works with SIP and IAX, and it shouldn't be impossible to make the zaptel driver recognize the stutter tone (if it doesn't already, I haven't poked into that source), a whole new configuration dialect or subdialect would have to be invented to convey the message between the two. Simple dialplan should be able to give you a 'one click to pickup external voicemail' type setup- it's the indication which Asterisk configs simply don't understand presently. Nice little project for 1.6, if there's enough interest- I'd put it in as a feature request in Mantis. -pbd -------------- next part -------------- An HTML attachment was scrubbed...

Paul I don't know why you are overcomplicating things. Just like asterisk can do the MWI for FXS it should be able to pick up the MWI form the Telco on an FXO, and then based on that asterisk should be able to turn on the MWI on any ohter device within asterisk. It would work something like this: /etc/asterisk/zapta.conf: detecttelcovoicemail=Sip/101,Zap/5 On 8/3/06, Paul Davidson <planac@gmail.com> wrote:> > > > > Date: Thu, 3 Aug 2006 14:52:53 -0400 (EDT) > > From: Bob Bosiljevac < bob@akn.ca> > > Subject: Re: [asterisk-users] Detecting voicemail from CO on FXO port > > and passing to H.323 phone.

Let me explain my motivation for the request.... We have a legacy POTS based PBX with FXO trunks and FXS station ports on the unit. It is running a very old release of the software and to upgrade to a version that will allow me to do VoIP will involve telephony card, software and licencing upgrades. The existing system itself works well and does pretty much everything we need it to do except has no VoIP capabilities. The long and short of it is, that by upgrading I would gain very little functionally other than VoIP for a lot of $$$$. So I thought of putting a Y jack on my station port and running it to an FXO port on another box running Asterisk. This way when my phone rings in the office, I can also ring whatever channels I want in Asterisk and if I make a call from a VoIP channel bridged to by station port, I can make calls as if I was sitting in my desk at the office. This, by far, has given me the most bang for the buck and is the quickest, dirtiest and least disruptive way to get VoIP terminals onto my system. The only thing missing from my little setup here is the ability to flash my MWI light on the VoIP phone in my home office when I have a message waiting on the office PBX. The phone at my desk in the office somehow has the flashing light; I figured there has got to be a way I can detect it and pass it on. BTW, I forsee the legacy PBX being phased out and the Asterisk "adjunct" taking on more and more of the role of the main PBX. Bob.
