Dear Team,

I see the discussion might be over but I have a query if you could assist.

I am working on an intra domain partitioned federation between Lync 2013 EE pool & IMP 2 node cluster (version 9.1)

I am facing some issue: When users are assigned to a subscriber node on IMP cluster Lync can't see the presence of those Jabber user. (Lync server getting request timed out message from IMP).

For tests I moved the same user to Publisher and Lync was able to see the presence.  To add when the Jabber user is assigned to subscriber node and is online (green). The presence viewer on IMP server is showing his status as Unknown.

As the presence viewer is showing wrong status for users assigned to subscriber I am believing its something wrong with subscriber node itself and not the federation configuration. (both IMP server have same Root CA signed certificates, DNS is fine)

My second Query is: In Lync logs they see below message from IMP when they search for a Jabber user, What timer can we change ?

SIP/2.0 423 Interval Too Brief   

"  According to RFC 3261, if a client (Lync) receives “SIP/2.0 423 Interval Too Brief” from server (Cisco CUPS), It should look at the Min-Expires header and retry the SUBSCRIBE request with an internal equal to or greater than the Min-Expires value advertised by Cisco. However, Cisco didn’t provide that information in the response back to the client, then Lync keeps retrying and getting 423 response."

Anil Sharma.
