RE: T21P E2 can't register(stuck at Registering ..)
hi

thanks for your information

from the pcap file , i can see that phone (192.168.1.127) send register message to SIP server (192.168.1.123) but get no reply from the server side , this is the reason why phone can't registered , see screen short below :

   

so , please check with the server side , whether the 200OK is send to the correct ip address and port ?

you can upgrade to the newest firmware and test again :

TKS & BR
