I have successfully installed Trixbox and I am having trouble trying to make the mentioned phone ring. The REN is 0.5 on the phone. However the phone rings either intermittently or you just hear a ticking. Either way it works directly off of the incoming line, but it does not work properly from the PBX. I am looking to boost the ring voltage or change the frequency through the zconfig.h file but can’t seem to find that particular module.
Can anyone help me find what I am looking for or how to boost the ring voltage in Trixbox. I am using the TDM22B card from Digium. Thank You.
