[Asterisk-Users] Help with transferring a second call from a snom 190

Hello List-

I'm having a problem getting snom 190 phones to transfer a call to
another local extension.
Here is the scenario:

A call (call1) comes in from the PSTN to (exten1). (via pri, if that
matters)
Another call (call2) comes in to (exten1).
(call1) is put on hold while (call2) is answered.
(call2) is then transferred to (exten2) using the "Xfer" button on the
snom phone. This results in dropping both calls.
  I've attached a sanitized sip trace from the snom phone for your perusal.

Thanks for any help you can offer.

Brian
