We have a problem with some of our T48G IP phones. Sometimes when we want to transfer a call to a co-worker the BLF buttons on the screen disappear and the phone reboots. This problem doestn occur always but a like 40% of the calltransfers.
The firmware is maintained by our sip provider firmware version is : 35.72.188.11.
The sip-provider has no idee what the problem could be.
We have looked in the phone it self , the network etc.

Anyone got any idee where to look ?

Any help would be appreciated ! Thanks

Greetings,

Michel
