Twinned call reset deskphone

Has anyone ever come across this....
When a call is sent to a deskphone that has twinning activated, the cal li placed to eth cellphone, but the user is unable to answer AND his deskphone then resets...
Any ideas?

rick,

I have never run into that issue before. What happens when they try to answer with the cell; no audio?

Thanks,

TE

i just performed a test call..
The transfer (twinning) to the cell phone works as far as ringing then fails
I get the call on my cell, and answer it, but I get no audio.
The person calling in continues to get ring tone as if the call wasn't answered!

Update -
I spoke with the customer this morning...
A call comes into phone A, the call is for phone B which is twinned to a cellphone.
The user transfers the call to phone B. After the call transfers, Phone A performs a reset.
This apparently doesn't happen everytime for every twinned call. But occurred twice yesterday.
I have asked the customer to note if and when it happens again with the details of all phones involved...

Anyone ever had this issue?
