Gatekeeper Controlled InterCluster Communication fails with Cause Code 47

Hi all,

 

We are trying to communicate two clusters using Cisco IPT endpoints and Jabber clients. It works fine with Non-Gatekeeper Controlled trunk, but not with a Gatekeeper Controlled one. Also, the trunk works fine with Cisco IPT to Cisco IPT calls, such as 99xx to 89xx or 79xx.

However, It fails with origCause_value = 47 when making a call from Jabber on iPad to Cisco 99xx on another cluster.

 

Following is the configuration : 

 

Calling Party : 

- Jabber Video for iPad 9.3.4

- Registered to CUCM v9.1.2 (ClusterA)

- Gatekeeper Controlled H.225 Trunk to ClusterB

- Region info : Audio Codec Preference List = Use System Default (Factory Default low loss)

                       Maximum Audio Bit Rate = G.729

                       Maximum Session Bit Rate for Video Calls = 384

 

Called Party : 

- Cisco 9971 registered to CUCMv8.6.2

- Non-Gatekeeper Controlled SIP Trunk to ClusterA

- Region info : Audio Codec Preference List = Use System Default (Factory Default low loss)

                       Maximum Audio Bit Rate = G.729

                       Maximum Session Bit Rate for Video Calls = 384

 

Please let me know if you need further details, I'd be glad to provide them. Thanks in advance.

 

Regards,

Fikri

Can you provide "debug gatek

Can you provide "debug gatek main 10" from your GK?

Hi Fikri,

Hi Fikri, Do you have a SIP trunk on both clusters or H323? From your description above, it's a little confusing. Please clarify that. Is it necessary for you to use a GK and not have a direct SIP trunk between the 2 clusters? (this would depend on the number of clusters you have) Cause 47 is usually a media resource issue or media layer timeout issue on the call manager. Please check where the disconnect for this call is originating. Thanks
