RE: SIP-T21P and SIP-T22P Registration problem in Tunnels
The version is 34.72.0.75 and also i tired setting the server expire . the problem is not registration , must change network setting that mean if it is DHCP must change to Static IP Address and if Static IP Address must change to DHCP after that will start to work . i do not have any problem with grandstream Phones . just this problem happen in yealink and i do not want to change all my phones . and also really it is hard every time change network setting phone ? so whats your solution for this Big Problem ?
