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

[Anthony Holloway]

Actually you don't want to set rfc2833 (pop quiz: rfc2833 is not the real
RFC number.  What's the real RFC number?  Don't google it, but reply if you
know!) on your CUCM SIP Trunk to CUBE.  You want No Preference.  It's a
setting right on the SIP Trunk, just scroll to the bottom of the settings
page.  Also, on your CUBE dial-peers you don't want solely rtp-nte either,
you want both rtp-nte and at least one Out of Band (OOB) option, like
sip-kpml or sip-notify (thought the latter requires a SIP Trunk Security
Profile change from default to allow unsolicited NOTIFY).
