Hi

Just taken hold of a 3510 Ip PBX and not know its history decided on a firmware upgrade. Trouble is its failed and now I get the following errors:

Invalid system prompt please check?

Voip module not ready please wait.

I try to carryout the upgrade again and it fails when it attempts to connect to the VOIP Module (tranfer fails)

Current firmware is: 3.5.9

Voip : 2.6.8

I have tried to downgrade it as well but it fails in the same place.

Any help would be very greatly received
