G723 encoding rate (6.3kbps or 5.3kbps)
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.
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.
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.
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.
This parameter, when set to Yes, will force random generation of both the local SIP and
RTP ports. This is usually necessary when multiple GXW-410xs are behind the same
NAT.
This parameter specifies how often the GXW-410x sends a blank UDP packet to the
SIP server in order to keep the "hole" on the NAT open. Default is 20 seconds.
NAT IP address used in SIP/SDP message. Default is blank.
IP address or Domain name of the STUN (Simple Traversal of UDP through NATs)
server.
