[Asterisk-Users] GS HandyTone Issue

[Stephen Rosebush]

I just got myself a GS HandyTone and it works great, it was a breeze to 
setup. My only issue is I seem to be hearing a humming noise on the line 
when I am in calls.. I am using the following:

*Product Model: * 	  HT286
*Software Version: * 	  Program--1.0.4.71    Bootloader--1.0.0.17 
   HTML--1.0.0.32    VOC--1.0.0.6


This is out of my sip.conf:

[201]
type=friend
secret=**********
host=dynamic
context=intern
canreinvite=no
dtmfmode=rfc2833
mailbox=201
disallow=all
allow=ulaw
allow=alaw

It seems to be on the device itself so I don't know if I am misconfigured?
