[cisco-voip] 8845's cannot make outbound calls

[Nick Britt]

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

*Debugs:*

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
