Extension in use

[Ava88]

Hi All,

The IP phone displayed "Extension in use" and can't be resume the service after the switch (PoE) power failure suddenly.

I had found that the problem is the CM 3.0.1 memorized the previous IP address of the IP phone and can’t be released. After the switch power recovered, the DHCP server assigned a different IP address to the phone. Even I am waiting around 1 hours but the IP phone can’t resume the service again. All the IP phone need to re-enter the “Extension & password” manually, Is there have any setting on CM or method to make it automatically.

Regards,
Ava88

Hi,

I had the same problem during one year ...
Are you shure to have Only one DHCP on the lan ?
If yes,Cut it or make MAC adresse lease
Normally, a dhcp should assign the last ip assets had.
