Email voicemail from asterisk

Nothing too flash - simple stuff and existing capability in TrixBox. Only problem I had was not being able to listen to the wav format recording on my cell (Android) or some desktops - the problem turned out to be common and resolving was simply a matter of changing a line of config, e.g. http://www.voip-info.org/wiki/view/Asterisk+Voicemail+as+email+using+sendmail

voicemail.conf

[general]
; Formats for writing Voicemail. Note that when using IMAP storage for
; voicemail, only the first format specified will be used.
;format=g723sf|wav49|wav
format = wav49|gsm|wav

The only other setting I changed (from default as part of this) was to not store the recording on the server (just email) - basically it is good to pick up the message remotely but having listened to it there is really no need to keep it (IMHO messages age so either listen or delete).

So in review there is now some basic IVR to ask who the message is for and once recorded the recording is emailed to said user. Happy campers.
