IP Office voicemail recording question 5

[Ian G]

Hello,

We have an IPO v9 with voicemail Pro.

We have a problem trying to get a prerecorded greeting message onto the mailbox of a user/hunt group.

When an out of office is recorded from the handset(connect to mailbox, option 3, option 2) a file appears in /opt/vmpro/greetings I can press option 4 and save it as looping which doesn't allow someone to leave a voicemail.

We then replace the file under /opt/vmpro/greetings with a professionally recorded greeting that has the same file name. This new greeting no longer loops and pressing option 4 does not enable looping. We can then drop the file recorded on the handset back into the folder and looping is restored.

How on earth can we get this pre-recorded file to loop? It seems like there is something in the wav file that makes it loop when it is recorded from a handset?

Any assistance is greatly appreciated!

Was the new file created using these settings?

PCM

8kHz 16-bit

mono

You need to edit the professional recording with a hex editor and enter on position 0x48 the value 01, see picture.
Then it will be played in a loop.

Hi Intrigrant,

Thank you for the help.

I tried this as you recommended but it didn't seem to work unless we are doing it wrong?
