Mediant 3000
Parameter Description
device does not interfere, but maintains an independent timer
for each leg to monitor the session. If the session is not
refreshed on time, the device disconnects the call.
[2] Not Supported = The device does not allow a session timer
with this SIP entity.
[3] Supported = The device enables the session timer with this
SIP entity. If the incoming SIP message does not include any
session timers, the device adds the session timer information to
the sent message. You can configure the value of the Session-
Expires and Min-SE headers, using the SBCSessionExpires
and SBCMinSE parameters, respectively.
Remote Update Support
[IpProfile_SBCRemoteUpdateS
upport]
Defines whether the SIP UPDATE message is supported by the
SIP entity associated with the IP Profile.
[0] Not Supported = UPDATE message is not supported.
[1] Supported Only After Connect = UPDATE message is
supported only after the call is connected.
[2] Supported = (Default) UPDATE message is supported during
call setup and after call establishment.
Remote re-INVITE
[IpProfile_SBCRemoteReinvite
Support]
Defines whether the destination UA of the re-INVITE request
supports re-INVITE messages and if so, whether it supports re-
INVITE with or without SDP.
[0] Not Supported = re-INVITE is not supported and the device
does not forward re-INVITE requests. The device sends a SIP
response to the re-INVITE request, which can either be a
success or a failure, depending on whether the device can
bridge the media between the endpoints.
[1] Supported only with SDP = re-INVITE is supported, but only
with SDP. If the incoming re-INVITE arrives without SDP, the
device creates an SDP and adds it to the outgoing re-INVITE.
[2] Supported = (Default) re-INVITE is supported with or without
SDP.
Remote Delayed Offer Support
[IpProfile_SBCRemoteDelayed
OfferSupport]
Defines whether the remote endpoint supports delayed offer (i.e.,
initial INVITEs without an SDP offer).
[0] Not Supported = Initial INVITE requests without SDP are not
supported.
[1] Supported = (Default) Initial INVITE requests without SDP
are supported.
Note: For the parameter to function, you need to assign extension
coders to the IP Profile of the SIP entity that does not support
delayed offer (using the IpProfile_SBCExtensionCodersGroupID
parameter).
User Registration Time
[IpProfile_SBCUserRegistration
Time]
Defines the registration time (in seconds) that the device responds
to SIP REGISTER requests from users belonging to the SIP entity
associated with the IP Profile. The registration time is inserted in
the Expires header in the outgoing response sent to the user.
The Expires header determines the lifespan of the registration. For
example, a value of 3600 means that the registration will timeout in
one hour and at that point, the user will not be able to make or
receive calls.
The valid range is 0 to 2,000,000. The default is 0. If configured to
0, the Expires header's value received in the user’s REGISTER
