Wan Reroute Backup Facility - Teldat -3Ge Quick Manual

A change in the value of this port affects the DHCP configuration. Option 43 must be modified to reconfigure the
Teldat-3Ge SIP agent listening port.
The SIP traffic transport protocol in the corporate router is UDP by default. The transport protocol cannot be changed
to either TCP or TLS. Since the Teldat-3Ge SIP agent only uses the UDP protocol as in a corporate Ethernet envir-
onment, it doesn't make sense to use protocols that further complicate the SIP transport.
Note
The Teldat-3Ge SIP agent always uses the UDP protocol to transport SIP traffic. It never uses TCP.
The UDP port value is configurable through the DHCP protocol (option 43,configured in the router).
For the system to operate properly, the SIP-IP telephones configuration must have the following para-
meters configured:
The SIP server IP address, which is the same as that configured in the backup TELDAT router.
The SIP server port to which the telephone sends SIP traffic, which is the same as that configured in
the corporate router.
The SIP server transport protocol, which is UDP.
Audio codification: G711 A-law.
Time between RTP packets: 10ms, 20ms, 30ms and 40 ms. We recommend using 20ms.
Deactivate Voice Activation Detection.
DTMF SIP INFO signaling out of band.

2.9 WAN Reroute Backup Facility

To prevent the router from routing backup traffic if the connection between the device and the Teldat-3Ge drops, you
need to add an entry to the router's WAN Reroute Backup feature (see manual Dm727-I Backup WAN Reroute ).
The configuration steps are as follows:
(1) Access the feature configuration menu:
(2) Enable the feature:
(3) Associate the Ethernet interface of the router connected to the Teldat-3Ge device and the PPP interface:
(4) Configure it as an inverse backup (i.e. if the main interface drops, the secondary also drops and if the main in-
terface activates, the secondary does as well).
Thus, the configuration part we need to add is:
feature wrr-backup-wan
; -- WAN Reroute Backup user configuration --
pair 1 primary interface ethernet0/0 secondary interface ppp1
pair 1 inverse-wrr
;
enable
exit

feature wrr-backup-wan
