I am using an Obi302 to interface my cordless POTS phones to my asterisk box. So far, initial setup and use is working fine but I am having one issue that I think relates to the Obi. When I place an outgoing call, if there is no remote answer after about 60 seconds, the call disconnects and a male voice announces no response from the number dialed. If I place the same call from one of the other devices on the PBX, the call rings until answered or terminated. I've looked in the Obi menus and found no obvious setting. Suggestions?
