ADVANCED USER SETTINGS

ADVANCED USER CONFIGURATION

The end-user needs to login to the advanced user configuration page the same way as for the basic

configuration page.

Advanced User configuration includes the end user configuration and advanced configurations including:

SIP configuration, Codec selection, NAT Traversal Setting and other miscellaneous configuration.

TABLE 7: ADVANCED CONFIGURATION PAGE DEFINITIONS

Admin
Password Administrator password. Only the administrator can configure the “Advanced Settings” page.
Password field is purposely left blank for security reasons. The maximum password length is 25
characters.
G723 Rate G723 encoding rate (6.3kbps or 5.3kbps)
V
oice Frames
per Tx This field contains the number of voice frames to be transmitted in a single packet. When setting
this value, the user should be aware of the requested packet time (used in SDP message) as a
result of configuring this parameter. This parameter is associated with the first vocoder in the
above vocoder Preference List or the actual used payload type negotiated between the 2
conversation parties at run time.
e.g., if the first vocoder is configured as G723 and the “Voice Frames per TX” is set to be 2, then
the “ptime” value in the SDP message of an INVITE request will be 60ms because each G723
voice frame contains 30ms of audio. Similarly, if this field is set to be 2 and if the first vocoder
chosen is G729 or G711 or G726, then the “ptime” value in the SDP message of an INVITE
request will be 20ms.
If the configured voice frames per TX exceeds the maximum allowed value, the BudgeTone 200
will use and save the maximum allowed value for the corresponding first vocoder choice. The
maximum value for PCM is 10(x10ms) frames; for G726, it is 20 (x10ms) frames; for G723, it is
32 (x30ms) frames; for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames respectively.
Layer 3 QoS This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or
Diff-Serv or MPLS.
Default value is 48. Its range lies from 0 to 63.
Layer 2 QoS This contains the value used for layer 2 VLAN tag.
802.1q / VLAN tag: Default value is 0. Range lies from 0 to 4095.
802.1p Priority value: Default value is 0. Range lies from 0 to 7.
*** The above 2 settings need to be supported on the network and then configured accordingly
on the GXW410x. Incorrect configuration will cause blocked access, which will result in Factory
Reset as the only option to renew access.
Local RTP port This parameter defines the local RTP-RTCP port pair the GXW410x will listen and transmit. It is
the base RTP port for channel 0. When configured, channel 0 will use this port _value for RTP
and the port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP and port_value+3 for
its RTCP and so on. The default value is 5004.
Use Random
Port This parameter, when set to Yes, will force random generation of local RTP ports. This is usually
necessary when multiple GXW410xs are behind the same NAT.
Keep-alive
interval This parameter specifies how often the GXW410x sends a blank UDP packet to the SIP server in
order to keep the “hole” on the NAT open. Default is 20 seconds.
Use NAT IP NAT IP address used in SIP/SDP message. Default is blank.
STUN Serve
r
IP address or Domain name of the STUN (Simple Traversal of UDP through NATs) server.
