XMPP Accounts
To change these fields on an existing account, you must first disconnect the account or turn Enabled off for the
account.
Keep Alive - Wi-Fi Interval A “keep alive” message is a mechanism for maintaining a “pinhole” through your firewall so that
the account registration is maintained. The interval specifies how often the message is sent (in
seconds).
If you are experiencing problems (for example, accounts become unregistered when using a Wi-
Fi connection), try setting this interval to a lower number such as 20.
Keep Alive - Mobile Interval Same as above, except the interval applies to registrations made over the mobile data network,
which can be made on an iPhone (but not an iPod) when you are not in a Wi-Fi zone.
Single Register • ON (default): Bria will register using a single register request.
• OFF: Bria will register using an unregister and a register.
Passive Session Timer Controls the use of session timers on SIP accounts. The session timer is used to determine if the
call is still active. Only choose Off if advised by your VoIP service provider.
• ON (default): Bria will not use session timers in any session, except it is explicitly required by
the remote party.
• OFF: Bria will use session timers in all sessions whenever the remote party supports and uses
it.
Connection Reuse • ON: Bria uses existing connections by including an “ob“ parameter in a header as defined in
RFC5626.
• OFF: Bria does not reuse existing connections.
Changing this setting might solve problems with dropping or holding calls. The default is On.
Enable IMS When ON, Bria supports the IP Multimedia Subsystem. The default is Off. Subject to VoIP
service provider. Only choose ON if advised by your VoIP service provider. When On, Bria does
the following:
• Populates authorization header upon every SIP request right away, instead of after challenge.
• Uses the SIP account domain for authorization realm.
