> I`m using several GXP2020 phones with newest Firmware 1.1.4.18. I had issues with phone locking up using 1.1.4.18. I've now gone to 1.1.4.22 and have eliminated that. > Asterisk Version: 1.4.11. Me too. Still testing 1.4.13 on a non-production system. > I use on every phone the 10000 as local port and in the rtp.conf
