I have an old PBX VM system that allowed me to wrap around during voicemail message selection. At the first message I am able to select "previous" and have it jump back to the last message (so I could keep playing them in reverse order). Similar for the last message, it allows me to select "next" and it will jump to the first message. This does not force a change to the order of playback it just allows you to go in a circle to get the message you want quickly.
This new feature is enabled by default but can be disabled in the voicemail.conf file. The system knows if there are no messages, or just one, and does not play the prompts for prev/next since it's pointless.
This patch is for Branch 1.4 (about the same version as 1.4.23).
Included english audio files are not correctly licensed for distribution with asterisk and should be re-recorded to match the other asterisk prompts anyway.
vm-goingtofirst.wav "Going to the first message."
vm-goingtolast.wav "Going to the last message."
Copy WAV files to /var/lib/asterisk/sounds (and transcode as needed).
Copy patch to main asterisk source directory and run patch -p0 <vm.patch and rebuild.
I now use Cepstral as a cost effective (but not free) solution.
Cepstral is easy to install, supports Linux and Solairs, works well, sounds good most of the time, and has a choice of voices including Allison (who records the packaged prompts for Asterisk). They offer full demo downloads so you can test a working setup before you pay for it. The current tested version is 5.1 (there are bugs, but I have worked aound many of them).
At their current prices, it's $30 for the each voice and a single queued FIFO license (no matter how may voices you have paid for). For additional "ports" (concurrent use) it's $50/each in addition to the voices. You have to pay for at least 2 total concurrent uses ($100) to get beyond the single port FIFO setup.
There are at least three ways to use Cepstral with Asterisk:
There are a few other applications for Cepstral/Swift including app_swift by Will Orton and app_swift by Darren Sessions

New stuff to be added: Dialplan variables to control the voice options.
Allows custom pager date format in voicemail.
This is a standard feature of 1.6 Trunk.
Patch file for 1.4 (branch): pagerdate14.patch.gz
Example in voicemail.conf just after emaildateformat:
pagerdateformat=%T %D
After an attended SIP transfer is completed play a beep.
This is a standard feature of 1.6 Trunk.
Patch file for 1.4 (branch): transfer_beep_14.patch.gz
Copy patch file to your main asterisk source directory
run patch in Asterisk directory: patch -p0 <transfer_beep_14.patch
rebuild and install
I just add this to the [global] section of the extensions config file:
ATTENDED_TRANSFER_COMPLETE_SOUND=beep
Here is my current (6-Apr-2009) app_fax.c (just copy it to the apps directory)
Install the new version of SPANDSP 0.0.6pre10 and apply the fax.patch
and rebuild the system as below.
You can't use the old app_rxfax/app_txfax code with the new SPANDSP.
If you are upgrading/replacing the older app_rxfax/app_txfax just remove them from your app directory and add app_fax in their place, then rebuild. You do not have to re-run the fax.patch.
