Voice Frames per TX 

This  field  contains  the  number  of  voice  frames  to  be  transmitted  in  a  single 
Ethernet  packet  (be  advised  the  IS  limit  is  based  on  the  maximum  size  of 
Ethernet packet is 1500 byte (or 120kbps)).  
 
When setting this value, be aware of the requested packet time (ptime, used in 
SDP  message)  is  a  result  of  configuring  this  parameter.  This  parameter  is 
associated with the first codec in the above codec Preference List or the actual 
used  payload  type  negotiated  between  the  2  conversation  parties  at  run  time. 
E.g., if the first codec is configured as G.723 and the “Voice Frames per TX” is 
set  to  2,  then  the  “ptime”  value  in  the  SDP  message  of  an  INVITE  request  will 
be 60ms because each G.723 voice frame contains 30ms of audio. Similarly, if 
this  field  is  set  to  2  and  the  first  codec  is  G.729  or  G.711  or  G.726,  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 
IP  phone  will  use  and  save  the  maximum  allowed  value  for  the  corresponding 
first  codec  choice.  The  maximum  value  for  PCM  is  10  (x10ms)  frames;  for 
G.726,  it  is  20  (x10ms)  frames;  for  G.723,  it  is  32  (x30ms)  frames;  for 
G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively.  
 
Please  be  careful  when  editing  these  parameters.  Adjusting  these  parameters 
will also change the dynamic jitter buffer.  The GXP has a patent dynamic jitter 
buffer handling algorithm. The jitter buffer range is 20 ~ 200 ms. 
 
Grandstream  recommends  using  the  default  settings  provided.    Grandstream 
does  not  recommend  adjusting  these  parameters  if  you  are  an  average  user.  
Incorrect  settings  will  affect  the  voice  quality.    Please  refer  to  the  Codec  FAQ 
at 

http://www.grandstream.com/pdf/FAQ-Codec.pdf

 

 for more technical detail. 

Layer 3 QoS 

This  field  defines  the  layer  3  QoS  parameter.    It  is  the  value  used  for  IP 
Precedence or Diff-Serv or MPLS.  Default value is 48. 

Layer 2 QoS 

This contains the value used for layer 2 VLAN tag.  Default setting is blank. 

Data VLAN Tag 

Default  is  0.  Enabling  the  Data  VLAN  filtering  will  help  reduce  the  load  on  the 
phone,  but  it  isn’t  necessary  in  most  environments.  This  is  primarily  for  VLAN 
filtering where tagged traffic will be forwarded to the DSP.  

No Key Entry Timeout 

Default is 4 seconds.   

Use # as 
Dial Key 

This  parameter  allows  users  to  configure  the  “#”  key  as  the  “Send”  (or  “Dial”) 
key.  If set to “Yes”, the “#” key will immediately send the call.  In this case, this 
key  is  essentially  equivalent  to  the  “(Re)Dial”  key.  If  set  to  “No”,  the  “#”  key  is 
included as part of the dial string. 

Local RTP port 

This parameter defines the starting local RTP-RTCP port pair used to 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 por1 for its RTCP; channel 1 will 
use  por2  for  RTP  and  por3  for  its  RTCP.  The  default  value  is 
5004. 

Use Random Port 

This parameter, when set to “Yes”, will force random generation of both the local 
SIP  and  RTP  ports.  This  is  usually  necessary  when  multiple  GXPs  are  behind 
the same NAT. Default is No.
