Help to setup Zetron zr320

[YT1DIM]

Helo all!

I need some help to get gr300 repeater to work with zr320 controller,radios are gm300 45w 16ch models,all basic functions as cor,cw id,tot,are working,but i cannot get the phone line interface to work.I use a gp300 sel5 radio with dtmf as remote radio,i set the radios and controller like discribed in gr300/500 user manual,but nothing,all i get is that when i call with phone,repeater patch the call to the radio,and i can heard a ringig tone,but cannot answer.Also when i manually connect repeater to the phone line (with button on the controller) then i can dial a number from handheld radio.Any help are welcome.

All the besti,Ivica.
