Local Ring Behaviour on Provisional Response
You can set the Mediatrix 1204 so that it starts or not the local ring upon receiving a “18x Provisional” response
without SDP.
This setting does not affect the behaviour when the “18x Provisional” response contains SDP, which allows to
establish an early media session before the call is answered.
X
To define the local ring behaviour on provisional response:
1. In the sipInteropMIB , set the sipInteropLocalRingOnProvisionalResponse variable to the proper
value.
SIP Credential
You can configure how the Mediatrix 1204 reuses the credential in different transactions of the same call or
registration. For instance, it may be required that a new SIP request does not reuse the credential negotiated
in the previous transaction of the same call or registration. For example, a re-INVITE will not reuse the
credential of the INVITE but will be challenged.
X
To set the Mediatrix 1204 not to reuse the SIP credential:
1. In the sipInteropMIB , set the sipInteropReuseCredentialEnable variable to disable .
If you set this variable to enable (which is the default value), the Mediatrix 1204 reuses the
credential negotiated in previous transactions.
Rejection Code
You can configure which rejection code the Mediatrix 1204 sends when it receives an INVITE and no SCN
ports are available. The rejection codes available are:
480 Temporarily unavailable
486 Busy Here
X
To select the rejection code used:
1. In the sipInteropMIB , set the sipInteropRejectCodeForNoRessource variable with the proper
rejection code used when all lines of the group are unavailable.
• temporarilyUnavailable: The “480 Temporarily Unavailable” rejection code is used.
• busyHere: The “486 Busy Here” rejection code is used.
The default value is: temporarilyUnavailable .
Figure 65: Local Ring Behaviour
Parameter Description
disable The local ring is not started on a “18x Provisional” response without SDP,
except for a “180 Ringing” message. This is the default value.
The 180 Ringing message is a provisional or informational response used
to indicate that the INVITE message has been received by the user agent
and that alerting is taking place.
Note : Using this default value means you are implementing a behaviour
that is different from previous versions of the Mediatrix 1204 application.
enable The local ring is started on any “18x Provisional” response without SDP.
