ADVANCED USER SETTINGS

ADVANCED USER CONFIGURATION

The end­user needs to login to the advanced user configuration page the same way as for the basic configuration page.

Advanced User configuration includes the end­user configuration and advanced configurations including: SIP configuration, Codec selection, NAT Traversal Setting and other miscellaneous configuration.

TABLE 8: ADVANCED CONFIGURATION PAGE DEFINITIONS

Admin	Administrator password. Only the administrator can configure the “Advanced Settings” page.
Password	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)
Voice Frames	This field contains the number of voice frames to be transmitted in a single packet. When setting
per Tx	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.
	For example 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 gateway 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
	Diff­Serv 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 RTP­RTCP 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	This parameter, when set to Yes, will force random generation of both the local SIP and RTP ports.
Port	This is usually necessary when multiple GXW410xs are behind the same NAT.
Keep­alive	This parameter specifies how often the GXW410x sends a blank UDP packet to the SIP server in
interval	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.
