Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
■ [0] = (Default) The Connection ("c=") line is displayed as
follows:
✔ Offer: In the session description only.
✔ Answer: In the session description and in each media
("m=") description.
■ [1] = For Offer and Answer, the Connection ("c=") line is
displayed only in the session description; not in any media
("m=") descriptions.
■ [2] = The Connection ("c=") line is displayed only in media
("m=") descriptions.
Note: The parameter is applicable only to the Gateway
application.
'Subject'
configure voip >
sip-definition
settings > usr-def-
subject
[SIPSubject]
Defines the Subject header value in outgoing INVITE messages.
If not specified, the Subject header isn't included (default).
The maximum length is up to 50 characters.
configure voip >
sip-definition
settings > coder-
priority-nego
[CoderPriorityNegotiation]
Defines the priority for coder negotiation in the incoming SDP
offer, between the device's or remote UA's coder list.
■ [0] = (Default) Coder negotiation is given higher priority to the
remote UA's list of supported coders.
■ [1] = Coder negotiation is given higher priority to the device's
(local) supported coders list.
Note: The parameter is applicable only to the Gateway
application.
'Send All Coders on
Retrieve'
configure voip >
gateway dtmf-supp-
service supp-
service-settings >
send-all-cdrs-on-
rtrv
[SendAllCodersOnRetriev
e]
Enables coder re-negotiation in the sent re-INVITE for retrieving
an on-hold call.
■ [0] Disable = (Default) Sends only the initially chosen coder
when the call was first established and then put on-hold.
■ [1] Enable = Includes all supported coders in the SDP of the
re-INVITE sent to the call made un-hold (retrieved). The used
coder is therefore, re-negotiated.
The parameter is useful in the following call scenario example:
1. Party A calls party B and coder G.711 is chosen.
2. Party B is put on-hold while Party A blind transfers Party B to
Party C.
3. Party C answers and Party B is made un-hold. However, as
Party C supports only G.729 coder, re-negotiation of the sup-
ported coder is required.
Note: The parameter is applicable only to the Gateway
application.
'Multiple Packetization
Time Format'
Determines whether the 'mptime' attribute is included in the
outgoing SDP.
■ [0] None = (Default) Disabled.
