DNS SRV Record Lock
Reference Manual (SIP Version)
Mediatrix 4104
173
DNS SRV Record Lock
You can configure the Mediatrix 4104 to always use the same DNS SRV record for a SIP call ID. As a result,
a call or registration always uses the same destination until the destination is unreachable or the unit receives
a different DNS SRV result.
To enable the DNS SRV record lock feature:
1.
In the
sipInteropMIB
, set the
sipInteropLockDnsSrvRecordPerCallEnable
variable to
enable
.
All messages during a call or registration use the same SRV record.
If you set this variable to
disable
(which is the default value), the Mediatrix 4104 rather follows the
behaviour as described in RFC 3263.
2.
Restart the Mediatrix 4104 so that the changes may take effect.
DNS SRV-Oriented Settings
The following parameters have an effect on the DNS SRV behaviour.
Table 110:
DNS SRV-Oriented Settings
Parameter
Description
sipInteropTransmissionTimeout
•
Has a dramatic effect should a server time out, since a
default 32 s delay would be introduced at every call.
•
Media5 recommends a maximum of 2-3 s when using DNS
SRV.
•
See
“Transmission Timeout” on page 271
for more details.
sipPenaltyBoxTime
If
sipPenaltyBoxEnable
is set to
enable
:
•
A “timed out” server is considered “not responding” for this
amount of time.
•
Can be seen as the time it will take to retry a server that
failed responding.
•
See
for more details.
sipInteropReuseCredentialEnable
If
sipInteropReuseCredentialEnable
is set to
enable
:
•
If there is not a shared database between servers, this
could lead to authentication problems because a
REGISTER and an INVITE can be sent to any server, not
necessarily the same one.
•
See
for more details.
