User's Manual 410 Document #: LTRT-89730
Mediant 3000
Parameter Description
[2] Handle Locally = The device handles SIP 3xx responses on
behalf of the dialog-initiating UA and retries the request (e.g.,
INVITE) using one or more alternative URIs included in the 3xx
response. The device sends the new request to the alternative
destination according to the IP-to-IP Routing table (the 'Call
Trigger' field must be set to 3xx).
Notes:
When the parameter is changed from 1 to 0, new 3xx Contact
headers remain unchanged. However, requests with the special
prefix continue using the device's database to locate the new
destination.
Only one database entry is supported for the same host, port,
and transport combination. For example, the following URLs
cannot be distinguished by the device:
sip:10.10.10.10:5060;transport=tcp;param=a
sip:10.10.10.10:5060;transport=tcp;param=b
The database entry expires two hours after the last use.
The maximum number of destinations (i.e., database entries) is
50.
The corresponding global parameter is SBC3xxBehavior.
Remote Early Media
[IpProfile_SBCRemoteEarlyMed
iaSupport]
Defines whether the remote side can accept early media or not.
[0] Not Supported = Early media is not supported.
[1] Supported = (Default) Early media is supported.
Remote Multiple 18x
[IpProfile_SBCRemoteMultiple1
8xSupport]
Defines whether multiple 18x responses including 180 Ringing, 181
Call is Being Forwarded, 182 Call Queued, and 183 Session
Progress are forwarded to the caller, for the SIP entity associated
with the IP Profile.
[0] Not Supported = Only the first 18x response is forwarded to
the caller.
[1] Supported = (Default) Multiple 18x responses are forwarded
to the caller.
Remote Early Media Response
Type
[IpProfile_SBCRemoteEarlyMed
iaResponseType]
Defines the SIP provisional response type - 180 or 183 - for
forwarding early media to the caller, for the SIP entity associated
with the IP Profile.
[0] Transparent = (Default) All early media response types are
supported; the device forwards all responses as is (unchanged).
[1] 180 = Early media is sent as 180 response only.
[2] 183 = Early media is sent as 183 response only.
Remote Multiple Early Dialogs
[IpProfile_SBCRemoteMultipleE
arlyDialogs]
Defines the device's handling of To-header tags in call forking
responses (i.e., multiple SDP answers) sent to the SIP entity
associated with the IP Profile. When the SIP entity initiates an
INVITE that is subsequently forked (for example, by a proxy server)
to multiple endpoints, the endpoints respond with a SIP 183
containing an SDP answer. Typically, each endpoint's response
has a different To-header tag. For example, a call initiated by the
SIP entity (100@A) is forked and two endpoints respond with
ringing, each with a different tag:
Endpoint "tag 2":
