Cisco Jabber lose connectivity to CUCM

[Bryan Wulfric]

Hi all,

I have CUCM, CUP in HQ and some Cisco Jabber users in remote site. At some time Cisco Jabber (phone mode) in remote site lose connectivity to CUCM, CUP. After the connectivity is restored, Cisco Jabber users can chat but cannot make a call. They have to sign-out then login again so that can make a call. Is there any way to make this automatic without having the users to sign-out then login again?

Thanks.

When connectivity is restored, does the client show registered to CUCM for softphone?

     If yes, what does the SIP traffic in the log file show when Jabber sends an INVITE?

     If no, are they able to click reconnect/apply settings to trigger a reconnect of that specific service?

It's expected that the client should generally reconnect on it's own, assuming no external factor is preventing it from doing so.  Also, what versions of the client/servers are in play here? How long is the connectivity loss and what is causing the interruption?
