Asterisk sometimes doesn't detect picked up call


We have a problem with our Astlinux box and 6 Linksys phones connected at this box. Sometimes when we got a incoming call the phones in the ringgroup are ringing, but when we pick up the phone we hear nothing and the other phones in the ringgroup keep ringing and had the same problem when picked up. Asterisk doesn’t detect that the call was picked up by some phone in the ringgroup. The debug log says nobody picked up before the timeout.

Anybody help?


Same here, it seems that Asterisk sometimes does not detect that a line has beens answered. We have it on a Grandstream phone with elastix.
