# *1 = Enable silence suppression in G.711

#

# 1-3 RESERVED. Must be set to 0.

#

# 4-5 DTMF Transmission Method

Thank you for your answer, but it did not fix my phone trouble. In fact, i have to disable voice detection in order to always let the voice pass through the phone.

At the moment, when i call an extension with my sip 7912 phone and the called person has answered, i do not hear his voice. I have to talk in my 7912 phone to establish the communication, and then everything goes nice.

So, i would like to shutdown voice detection or change the voice detection threshold.

regards.

Philippe.

Hello,

The info (excellent as always) provided by gogasca indeed it is telling you how to disable VAD by the use of a configration file. You will a small package on (available to CCO registered users) that contains an utility used to generate the binary config, a tagging file needed by the same. Also incuded, bmp to logo utility.
