Subscribing to the presence status of a contact informs the Cisco VCS that the client should be notified
when the contact's presence status changes.

Movi will subscribe and publish when 75% of the specified time intervals have elapsed. The client will be
automatically subscribed to the presence status of any contact that is added.
In addition to these periodic messages, Movi will also publish presence information when the user's
status has been changed, either manually or because the user is in a call.
See the "Presence" section of the
presence server.
SIP keep alive
To make sure that the connection between the Movi client and the Cisco VCS remains open and does
not get closed by a firewall as an idle connection, Movi sends SIP Keep Alive messages.
By default the interval for these messages is 24 seconds. To configure the SIP Keep Alive Interval:
1. In Cisco TMS, go to
Systems > Provisioning >
2. Click on the group or user you want to provision and find the
3. Change the SIP Keep Alive Interval configuration if it exists, or add one
Losing connection
If Movi gets an indication that the connection has been lost or is unable to continue registering to the
Cisco VCS, Movi will sign out and display the sign-in screen.
If the Sign in automatically box is checked, Movi will attempt to sign in again. The first attempt will be
one second after connection got lost, the second attempt after two, the third after four, then eight and
next sixteen. From the ninth attempt onwards, Movi will try to sign in only once every 5 minutes, to
prevent putting too much strain on system resources.
Searching for a contact
Every time a user types a character in the search field of the Movi client, Movi queries the TMS Agent on
the Cisco VCS, and the TMS Agent answers with matching results.
Note: Phone book search results are determined by the Cisco VCS/TMS Agent and dependent on Cisco
VCS version.
When a search result is selected, Movi will also query the Cisco VCS for the presence status of that
contact.
Call setup
Call setup is communicated using SIP messages passed through the Cisco VCS. The following
describes how the call's attributes are determined during call setup.
