<br><br>Paul I don't know why you are overcomplicating things. Just like<br>asterisk can do the MWI for FXS it should be able to pick up the MWI<br>form the Telco on an FXO, and then based on that asterisk should be<br>able to turn on the MWI on any ohter device within asterisk. It would

<br>> What that would imply is that Asterisk could be bridged (with configuration,<br>> not code) to an external voice mail system- most of the focus here is using<br>> Asterisk as a voicemail system for other PBX's. While Asterisk does have a
<br>> way to indicate voicemail to a given phone (I haven't tried an h.323 phone,<br>> but it definitely works with SIP and IAX, and it shouldn't be impossible to<br>> make the zaptel driver recognize the stutter tone (if it doesn't already, I
<br>> haven't poked into that source), a whole new configuration dialect or<br>> subdialect would have to be invented to convey the message between the two.<br>> Simple dialplan should be able to give you a 'one click to pickup external
<br>> voicemail' type setup- it's the indication which Asterisk configs simply<br>> don't understand presently.<br>><br>> Nice little project for 1.6, if there's enough interest- I'd put it in as a<br>> feature request in Mantis.
<br>><br>> -pbd<br>><br></blockquote></div><br>You're right- that is a simplified way of putting it (a subdialect, as it were). Point is, to my knowledge (I'll happily stand down if it is) that support isn't presently there, and there hasn't been a huge rush of people looking for it. It's really only useful in the extremely small office (SOHO) situation, or to someone who wants to integrate a non-asterisk VM system with Asterisk- the converse of what most people here generally want to do. (I'd have to wonder why you'd do that, since Asterisk VM works so well, and is easily customized to your needs). I do have customers who might see some advantage to it- but more in a unified messaging sort of way, so that they could 'collect' all their voicemail, answering machines, etc, into one storage location (asterisk) and use that to transport it out again. Plus, as someone else pointed out- it might not be stutter tone- there are a few different ways of signalling voicemail on analog lines. All of which should be possible to handle in Zaptel drivers- but more research would have to be done.
