I have an IAX connection from my telephony PBX running asterisk to one
of my Allstar nodes running Allstarlink.
It works as expected when connecting using a analog telephone
instrument connected to an analog telephone adapter (ATA). However,
when using a Cisco VOIP phone, I hear two quick beeps every 15 seconds
while connected to the Allstar node.
Does anyone know what these tones might be and how to eliminate?
