Asterisk Voicemail

Created by: rgauss,Last modification on Fri 04 of Jul, 2008 [20:24 UTC] by JustRumours

Asterisk Voicemail

Features

  • Password protected
  • Separate away and unavailable greetings
  • Default or custom greetings
  • Multiple mail folders
  • Web interface for checking of voicemail
  • E-mail notification of voicemail with audio file attachment
  • Voicemail forwarding
  • Visual message waiting indicator (MWI)
  • Message waiting stutter dialtone

The number of messages for each voicemailbox is limited to 99 messages. Starting with Asterisk 0.7.1 the system now plays a prompt warning the user that the mailbox is full and cannot record any more messages.

Enhanced voicemail

New features (as of April 28, 2004)
  • Option to have the CID of the caller heard before the voicemail
  • Option to allow an operator to be reached after leaving a voicemail
  • Option to review, rerecord, or save voicemails after leaving them
  • Option to review, rerecord, or save busy, unavailable, and name prompts.
  • Option to allow dialing out from within voicemail
  • Option to allow calling back of the person who left voicemail (with the correctly formatted contexts in extensions.conf)
  • Group voicemail (voicemail broadcast)

VoiceMail contexts.

The context defined in the voicemail.conf corresponds to entries in the channel configuration file, i.e. zapata.conf and sip.conf which require the context to be appended to the mailbox when using VoiceMail2.

Configuration lines for a voicemailbox in voicemail.conf:
[YourVoicemailContext]
210 => 5555,John Smith,jsmith@yourdomain.com

Line in zapata.conf or sip.conf:
mailbox=210@YourVoicemailContext

The location of saved messages also changes with the context:
 /var/spool/asterisk/voicemail/YourVoicemailContext/210/INBOX

VoiceMail includes a time stamp with the message by default.

When listening to a message you'll hear when it was recorded.


Please note

  • Voicemails are saved on the server in all formats specified in voicemail.conf, but only the first format specified is sent as an attachment to the email.
  • The /contrib/scripts directory of /usr/src/asterisk contains a PERL script that can be applied to regularly expire too old voicemail messages

333Low volume in VM files

by pozar, Saturday 14 of June, 2008 [22:47:33 UTC]
Seems that levels can go all over the place with voicemail messages. To some degree, some playing with incoming PSTN levels will help but then there is all the other sources you can get VM from such as other extensions, etc.<P>

It would be nice if * had some hooks for post processing the VM files before they get sent out as mail and dropped into the VM folders on *. Since there isn't, what I have been doing is running "normalize" on the VM folders so the files sound good if you are picking up the VM from your phone. It is a simple root cron job that looks like: 
   0/5 * * * * /usr/bin/find /var/spool/asterisk/vm/ -type f -mmin -10 -name 'msg*wav' -exec /usr/local/bin/normalize {} \; > /dev/null 2>&1 &


In this, find will be run every 5 minutes and look for message wave files newer than 10 minutes. If it finds any it will run "normalize" on it.<P>

I have also told asterisk only create wav files in voicemail.conf: 
    format=wav

You really don't need gsm or other formats. Asterisk does fine with just wav.<P>

BTW... Normalize can be found at:<P>

If you want to allow users with iPhones to listen to the voicemail attachment immediately, set the format to :

format=wav|wav49|gsm

Having wav as the first option means its the one emailed, and this option allows playback of the attachment on Apple's iPhone, so users can listen to their voicemail's as soon as they get them!

333Help!

by ch33ky_m0nk3y, Thursday 07 of June, 2007 [14:18:12 UTC]
Ok, i am right newbie to the asterisk environment, with no past experience of programming at all, but i have some friends that i can ask for help, but they cant help with everything.

I have a few phones set up on asterisk and i am playing around with the idea of having a text message sent or an email sent when a voicemail is received.

I have managed to send an email to an internal email on the network but as far as it goes for EXTERNAL... nothing, no emails what so ever.

I am completely STUCK!

Which is easier... voicemail to SMS or voicemail to email?

Any help would be much appreciated.

Thanks,

Simon

333Re: Voicemail calls cut off...

by mjgolli, Thursday 30 of November, 2006 [02:11:09 UTC]
I had the same problem, too. If you call vm and the first part of the announcement is cut off, add a wait(1) statement before the actual voicemail() or voicemailmain() calls. That should help. You'll be able to hear "Comedian Mail" rather than "median mail"!

<p>
It appears the designer of Comedian Mail was not more familiar with Meridian Mail than Audix. This is unfortunate because Meridan Mail was terrible, we used Calais on our Nortel stuff, Audix on the Lucent/ATT/Avaya/Whoever. By far the easiest mail system to use was Audix. Very intuative. I've considered re-engineering the VM system to be more audix like, but I'm not sure what direction all this stuff is headed, but Comedian Mail requires way too much navigation. I also miss *T (*8) transfer *D(*3) delete, etc. Lucent switches were annoying, but the voicemail was top notch.

<p>
Anyone else out there interested in a more Audix-like setup. I'm not sure I still have any training materials floading around, but I'm strongly interested in doing this.</p>

333Scheduling notification

by pwf1960, Thursday 15 of June, 2006 [09:38:39 UTC]
Is there any way to change the way notification works, based on the time of day? For example, you have a support group that has afterhours support from 1700 to 2200 hours
Monday through Friday. Is there a way to have a support mailbox that sends notifications only during that time frame?

333Setting up Voicemail to email attachments

by gurowar, Tuesday 11 of April, 2006 [15:49:39 UTC]
Question...I'm trying to set up voice mail so that it emails me when someone leaves a message. I have a Norstar system and the phones are forwarded to 7846 on no answer and 7946 on busy. I see that the voice mail picks up and you can leave a message but it never emails me the wav file. I set up the email address in voicemail.conf already but still don't get any messages what am I miss???
