I just upgrade to Asterisk 1.4.25 from 1.2 and now our Grandstream BT200 phones are not registering. I’ve tried using a static IP and dynamic and neither work.
sip show peers just shows (Unspecified) under Host when using DCHP for the phones. I also updated the firmware, but that didn’t help either. They worked perfectly fine with Asterisk 1.2. I’m running CentOS 5.3 on a Sun Ultra20. Any ideas as to what’s wrong?
