404 Not Found from Jabber clients on Incoming calls from PSTN

[00u1c1e8sgNfbgbZ15d7]

My customer has a CUCM cluster ( Pub & SUB) System version: 12.5.1.15900-66.

PSTN access provided by SIP connection to one CUBE.

Customers using jabber can establish outgoing calls to PSTN with no issue.

Customers using jabber are UNABLE to receive inbound calls from PSTN, when you call from outside no ring for some seconds and call drops.

Call flow:

PSTN --SIP --> CUBE --SIP --> CUCM cluster ( pub & sub) --> Jabber client

From initial validation we found:

a) Calls are arriving properly to CUBE ( no DID issue from SP).

b) Inbound CSS of CUBE has access to internal DN's partitions.

c) After proper digit analysis by CUCM , calls are forwarded to correct internal DN ( and Jabber client).

d) Destination Jabber client is responding initial SIP INVITE with "404 Not Found" message and once CUBE receive it, it sends a 503 Service unavailable to PSTN caller, and call is disconnected.

e) When I configured internal DN to "Fwd all calls" to voice mail, inbound calls from PSTN get access to customer voice mail greeting and PSTN caller can leave a message.

f) I validated that CUBE has network connectivity to Jabber client's network.

Any recommendation will be welcomed, to continue troubleshooting

Thanks in advanced for help

Hi,

Can you please specify if it happens when in MRA or in local LAN? Please also tell us which Jabber version you are using and if it's Mobile Client or Desktop Client. Last.. please check the Security Profile configuration on Jabber Phone configuration page.

Please let us know

Thanks

Regards

Carlo

Thanks for reply.

They are connected on local LAN ( no MRA).

From CUBE i have network connectivity to them, and as I said before they can establish outgoing calls on that CUBE

They are using Jabber version 14.0.0.55563

Their Jabber Device Security Profile is: Cisco Unified Client Services Framework.

Hi,

Please do the following steps:

- Reset one of your jabber clients.

- Login to Jabber again

- Make an Outbound call

- Make an Inbound call to that client

- Generate a PRT and attach here.

Thanks a lot
