T22P massive lag

[papachumba]

just to add to this,
i noticed this lag when:

I had the phones connecting over VPN to the phoneserver.
Then I repointed the server to a live IP which doesnt go via VPN and punched this setting in the phones.
After a few days, the phones will slow down, menus will be laggy and finally users will not be able to make/receive calls.
After a reboot, everything goes back to normal.

I think this bug goes away if you fully disable VPN (in my case), as above VPN stayed active when the slowdown happened (even though SIP traffic wasnt taking that route any more)
This was all on previous firmware version - 7.72
