Jabber Phone mode only for Iphone 503 service Unavailable

Hello all,

 

I'm trying to connect iphone jabber app v12.5  to cucm v8.6.2 in phone only mode without IM and Presence servers.    The iphone is able to register to cucm, but when I make calls from the iphone jabber,  I get a fastbusy when the remote phone answers the call.    The attached packet capture shows that the cucm server sends a 503 service unavailable even though the jabber client has successfully registered to cucm. 

 

Can any tell me what's missing?

Hello lllini,

Jabber version 12.x support UDS with CUCM version 10.5 or later. Jabber 12.x with CUCM version 8.6 will not work.

You can use the lower version of Jabber to work with CUCM 8.6.
