228 Mediatrix 1204
Available values are from 1 s to 86,400 s (one day).
This value does not modify the delay before a re-PUBLISH.
• The delay is the value of the Expires header in the 200 OK response to the PUBLISH
minus the value set in the
sipPublicationRefreshTime variable.
• If the Expires header in the 200 OK response to the PUBLISH is not present or badly
formatted, then the delay is the value of the variable
sipInteropDefaultPublicationExpiration minus the value set in the
sipPublicationRefreshTime variable.
See “Refreshing Publications” on page 227 for more details.
Setting the variable to 0 disables the expiration suggestion.
Default Publication Expiration
You can configure the value of the default registration expiration.
X
To configure the default publication expiration:
1. In the sipInteropMIB , set the sipInteropDefaultPublicationExpiration variable with the default
publication expiration.
The delay before a re-PUBLISH is the value set in the sipInteropDefaultPublicationExpiration
variable minus the value set in the sipPublicationRefreshTime variable. See “Refreshing
Publications” on page 227 for more details.
2. Restart the Mediatrix 1204 so that the change may take effect.
Interop Parameters
The interop parameters allow the Mediatrix 1204 to properly work, communicate, or connect with specific IP
devices.
Call Transfer Capacity
The following parameters allow you to define how the Mediatrix 1204 handles call transfers.
Call Transfer Version
The Mediatrix 1204 executes transfers by using the methods described in draft-ietf-sip-cc-transfer-05.txt . This
draft version contains several enhancements over the previous ones. Among others, it is possible to use the
Replaces header to provide a more seamless attended transfer to the user. See
“Replaces Configuration
Setting” on page 228 for more details.
This feature is currently located under the mediatrixExperimental branch of the MIB structure. See “MIB
Structure” on page 111 for more details.
Replaces Configuration Setting
You can configure how to use the Replaces header mechanism used in a transfer. When supported by the
target of the transfer, the Replaces header mechanism ensures a more seamless transfer by permitting the
initiating party to effectively replace a current call by another instead of disconnecting the call to be replaced
and creating a second call. This allows you to control how the Mediatrix 1204 interoperates with other vendor’s
products and older Mediatrix units.
This feature is currently located under the mediatrixExperimental branch of the MIB structure. See “MIB
Structure” on page 111 for more details.
