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
