RE: Phones Lose Registration
hi

there are many reasons that may cause the phone register failed , like network lost , password not correct and so on , for this issue , please see the suggest below :

1. check to confirm that the network of the customer is fine when the phone register failed
2. upgrade the T2X to the newest firmware ,firmware download link :
http://support.yealink.com/documentFront...isplayPage
click according to your model
3. reset the phone to factory
4. set the Server Expires to a shorter value like 30, path : web page -> account -> Register -> Server Expires

if all the above solution can't solve your issue, please provide us the trace file for future analysis,trace file including pcap file, config bin and syslog file , and we need three of them provide at one time.

for how to get them , please refer to the FAQ below:

send the trace file to support@yealink.com

TKS & BR
