MtasUint00001to065535DT |
-
mtasSipAsGenericPort
=
5094
-
This attribute defines the AS generic SIP port number which can be used to trigger MMTel AS, SCC AS and the NW AS. The trigger in HSS must contain the Route parameter 'as=' specifying the name of the AS to be invoked. This port can also be used for PSI functionality on the MA interface.
Dependencies: None

MtasSipCallOutOfBlueRoutingDT |
-
mtasSipCallOutOfBlueRouting
=
S_CSCF
-
This attribute defines the MTAS behavior for terminating Call out of the Blue requests towards a CSCF.
- If the S-CSCF supports User Unrelated ISC Routing, than the terminating Call out of the Blue can be sent to an S-CSCF where the user is not registered.
- If User Unrelated ISC Routing is not supported, such request is sent to I-CSCF.
Dependencies: This attribute cannot be set to I_CSCF (1) if mtasSipIcscfName is empty.

MtasTimerSec00000to000180DT |
-
mtasSipCancel2FinalResponseTimer
=
5
-
This attribute defines the maximum time allowed after MTAS receives a 200 OK to a CANCEL message and does not receive a final response to the invite transaction. The value 0 is to be avoided due to robustness issues. Note that if the value 0 is used and the call setup time reaches 10 minutes, then the Node Control function "Hanging Process Supervision" will terminate the process unconditionally and tear down the call setup.
Takes effect: New session

MtasBooleanDT |
-
mtasSipChangeRefresherRoleInReinviteAndUpdate
=
true
-
This attribute defines the MTAS behaviour of changing the refresher role for reINVITE and normal UPDATE in an exception case. If this attribute is disabled, then when MTAS sends out the reINVITE or normal UPDATE, it will not change the role of refresher parameter which means that it will be same as the previous negotiated result. Enabling the attribute, an exception will occur if the previous negotiated result is the remote side as refresher. In this case, MTAS will change the refresher role to empty, i.e. no refresher parameter in the reINVITE and normal UPDATE.

MtasUint01024to065535DT |
-
mtasSipCnamePort

Dependencies: The mtasFunctionAdministrativeState must be locked in order to allow change. To open traffic for a new port number, remove VIP Mappings for the old UDP and TCP port number and then insert VIP Mappings with the same data for the new UDP and TCP port number.

mtasSipEnableSessionRefreshForEarlyUpdate
=
true
-
This attribute defines the MTAS behavior of session refresh message handling for early UPDATE. If this attribute is set FALSE then when MTAS receives an early UPDATE sip message with unchanged SDP or empty SDP, MTAS will not treat it as session refresh message, which means try to forward it out. Setting attribute to TRUE means that MTAS will treat this kind of early UPDATE as session refresh message (legacy behaviour).

The appended <port> is defined as "0", or 4 to 5 digits forming a number with the highest value 1024:65535. Port = 0 means that a domain name is specified, so the port to use is fetched from DNS with SRV lookup.
Numerical IPv6 addresses must be enclosed with brackets for example [1080::8:800:200c:417A]:8080. When port is not specified MTAS uses the 5060 default SIP port.
Dependencies: This attribute cannot be set to empty if mtasSipCallOutOfBlueRouting is set to I-CSCF (1) or if mtasCcAdministrativeState is set to UNLOCKED (1) or if mtasDtmAdministrativeState is set to UNLOCKED (1) or mtasParlayX3pccAdministrativeState is set to UNLOCKED (1).

This attribute defines, before receiving the final response on initial INVITE, if MTAS is transparent for the received early dialog BYE when it has more active early dialogs.
If so, by enabling this attribute, the received early dialog BYE will be forwarded out, and disabling the attribute means MTAS will just answer this early dialog BYE with 200OK.
Otherwise when there no more active early dialogs, regardless the setting of this attribute, the early BYE will be converted to CANCEL. In case that the final response on initial INVITE has been received, then the early BYE will just be answered with 200OK regardless the setting of this attribute.
