Has anyone ran into this problem? I'm testing with a SIP9971 phone. In order to make PSTN calls we have to disable video on the device configuration page. When video is enabled, calls to landline work but no ringback. Local cell calls I get a busy signal. Long distance cell calls we get number cannot be completed as dialed from CM. All other models work fine. I'm thinking it fails because of what is sent in the Setup message or type being sent. Gateways are H323 with PRIs.

Go to the voice ports in the H323 GW and type the following command:
bearer-cap speech
Otherwise you'll send the SETUP with video capabilities and the call will fail.

No digit manipulation is done at UCM. Gateway is local, H323. I'm attaching debugs and dial-peer config. In this case the number is an LD number. It is matching the LD dial peer.
Device pool is configured for G711 and G729. I also changed the phone to G711 only and it failed too.
Again, when video is disabled under Video Capabilities, it works fine.
I've highlighted the number I'm calling to.
Call flow
9971 reg on UCM -> Route pattern -> RL -> H323 gateways -> PRI group

Hello,
I have checked the debug you attached. And i see the reason of disconnect is unassigned/unallocated number, which is caused because you are not sending the call type and plan. I have seen also there is another call which was sent successfully to the PSTN.
Now you need to check the following, when you disable the Video from the phone how is the debug looks like, and when you enable the video how it looks like also.
The failed one should look like this:
Calling Party Number i = 0x2181, '7132076553'
Plan:ISDN, Type:National
Called Party Number i = 0x80, '19563690097'
Plan:Unknown, Type:Unknown
The working one:
Calling Party Number i = 0x2181, '7132076553'
Plan:ISDN, Type:National
Called Party Number i = 0x80, '19563690097'
Plan:ISDN, Type:National
I think your PSTN expect a proper Plan and Type from you.
Please let me know with the result of both calls.
Best regards,
Nizar

There is also an option to under the gateway to retry video as audio call. check that if it isnt already.

I had the exact same issue before and, as java pointed out, adding the "bearer-cap Speech" statement under the voice-port resolved it.

Wo~ Really work on this command ...
Why MGCP VG is no this issue?
But H323 VG have this issue?
VG(config)#voice-port 0/0/0:23
VG(config-voiceport)#bearer-cap speech
bearer-cap speech ... What is the meaning on this command?
