We have a customer with a OS7200S. We installed this system about 5 years ago.
We configured one mailbox (EXT14 - MBX 14). This was enough.

Now the customer needs more mailboxes and he wants to record calls with the integrated voicemail.
So I tried today to configure this today.
First I programmed a button CR on the phone, which has a mailbox since 5 years.
I got the message COS problem. So I looked into the COS groups. All phones are in COS group 1 and I switched VM Reocrding to YES. I tried again and everything worked. Great.

Then I made 3 new mailboxes. I tried with one phone. I changed the password and I programmed a button CR.
I called the phone but I couldn't record the call. OK. I made an extention in the voicemail system and tried again, without success.
I tried with another new mailbox, also no success.

So I decided to make a reboot of the OS7200S. After this the new created mailboxes and extensions are away. There was only MBX 14 and EXT 14.
I create a new mailbox and extension for extension 24 and tried again. No success.
I compared the credentials of mailbox 14 with mailbox 24. They are identical.


Why is it not possible to record calls with the new created mailboxes? And does I need for call recording also an extension?

Many thanks and best regards, Peter

Hi Peter,

Make sure 'BOTH' is selected in MMC751 for the new mailboxes

Hi Lee, many thanks for your support. Great. I do forget very often this point and create the mailboxes directly in 8.1.
In the future I will do it with MMC751.

Many thanks, it worls now perfectly.
