Sorry Nick, I did not see towards the bottom where you had provided your solution.
Essentially what happened is the phone is trying to negotiate a video payload with the PSTN in for your PRI. The carrier is dropping that like a hot tater.
So you can declare the bearer capabilities as speech only for that voice port, or you can adjust the regional setting in call manager so that there is no video bandwidth available for the call when that 8845 dials out.
I personally am a fan of taking care of this in communications manager. Either way, I wouldn't go about the fix by disabling video on the handset in case you actually did want to use video for onnet calls or through trunks but do support video payloads.
Thanks,
Ryan

Just ran into this one....
Topology:
8845 > CUCM 8.6 > H323 GW > T1 > PSTN
Desc of problem: Video capable handsets cannot make outbound calls where as non video phones work fine. Calls are passed to h323 GW OK
Troubleshooting steps:
Devices have same Class of service/device pool/within subnet
Config:
voice-port 0/0/0:23
!
interface Serial0/0/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
isdn supp-service name calling
isdn outgoing display-ie
trunk-group PRI-TGroup
no cdp enable

Resolution:
Video handsets are sending Transfer Capability = Unrestricted Digital where as non video handsets are sending the transfer capability = speech
Fix
Disable video on handsets
or
implement on the t1 voice port
voice-port 0/0/0:23
bearer-cap Speech
