• If a check sync NOTIFY containing the parameter "reboot=false" is received by the phone,
the phone will reload the configuration files without rebooting. Any dynamic parameters in
the configuration files (i.e. those that do not require a reboot for changes to be applied) will
be synchronized accordingly.
MICLOUD TELEPO MUSIC ON HOLD SUPPORT
MiCloud Telepo "music on hold" functionality is supported on the 6800 Series SIP phones.
"Music on hold" is a feature whereby calls placed on hold are provided with an audio stream
(often music) that is played back to the held party for the duration of the hold.
Administrators can use the global "
sip moh server
" parameter or per line "
sip lineN moh
server
" parameters to enable the music on hold feature. If a media server SIP address
(excluding the domain name) is defined using the parameter, the phone will use the specified
server to provide an audio stream to any held parties. The audio stream will be offered in all
cases when a remote party is placed on hold (i.e. when placed on hold directly, when placed
on hold while performing a transfer or conference, or when the local party switches lines).
Enabling Music on Hold Functionality
Use the following procedure to enable music on hold feature:
For the specific parameters you can set in the configuration files, see Appendix A, the section,
“MiCloud Telepo Music on Hold Settings” on page 315.
UAC SESSION REFRESH SUPPORT
With certain networks, a Session Refresh is required to be performed by the User Agent Client
(UAC). To accommodate this, a new configuration parameter “
sip force uac session refresh
”
has been introduced. When the parameter is enabled and an incoming initial INVITE with a
Session-Expires header with no refresher parameter is received, the Session-Expires header
and the refresher=uac parameter are added to the 200 OK response as per the following format:
Session-Expires: n;refresher=uac
Note:
The feature is applicable to the 6800 Series SIP phones when used in conjunction
with the MiCloud Telepo for Service Providers call manager.
