RE: Failed registration, factory reset
hi

normally , this kind of situation happened when something wrong was happened to the network or the sip server and then the mistake solved quickly by itself.

you can try to adjust the following parameters to see whether it take effect.

1. Account -- Register -- Server Expires turn to 30
2. Account -- Advanced -- Keep Alive Interval(Seconds) turn to 30
3. Account -- Advanced -- SIP Registration Retry Timer(0~1800s) turn to 30

all the above parameter can be found on the last firmware , firmware download link :

http://support.yealink.com/documentFront...isplayPage

click according to the corresponding model

a factory reset after upgrade is needed.

if the issue still exist , then we need trace file for future analysis , please send them to support@yealink.com

trace file including pcap file, config bin and syslog file , for how to get them , please refer to the FAQ below:
