[cisco-voip] Inbound calls to H323 using CCD over SAF fail with dead air

[Jeffrey Girard]

This is a lab network.



I have two CUCM 8.6 clusters using CCD over SAF.  Phones attached to both clusters are able to call back and forth.



I just added a H323 gateway into the mix - running CCD over SAF.  Two phones registered to the CUCME.



Outbound calls from the CUCME to anywhere all succeed.



Inbound calls from anywhere (both clusters) all fail with dead air.



Both RTMTs show that the pattern (51XX) is reachable.



SAF neighbors are all present as they should be.



A debug voice dialpeer on the CUCME shows no activity when a call is placed inbound to the CUCME.



Stripped CUCME config is below.



Any thoughts?
