[cisco-voip] Ported Numbers to SIP call handler transfer is not working correctly.

[Anthony Holloway]

Ding ding ding!  Winner!  I wonder why Cisco doesn't update the CUCM UI.  I
was looking for DTMF support in a Telepresence Admin Guide for like an SX20
or something, and I couldn't find RFC2833 mentioned anywhere, but it did
mention RFC4733.  Anyway, that's all the trivia I have for now.
