T46G 28.80.0.95 BLF Not Working

[Yealink_Michael]

hi

sorry for the inconvenience

for this issue, it may caused by two reasons :

1. account registered failed after network disconnected , caused BLF did't work

for this situation it is advised to shorter the sip sever expire time in order to re-register after network comes back ASAP !
auto provision sentence :
--------
account.X.sip_server.Y.expires =
--------
//It configures the registration expiration time (in seconds) of SIP server Y for account X. value range : Integer from 30 to 2147483647 , default value is 3600
Example:
account.1.sip_server.1.expires = 3600//

2. BLF subscribe expire too long which make the phone didn't send subscribe to update the status when network comes back !

solution : shorter the expire of BLF subscribe time
---------------
account.X.blf.subscribe_period =
---------------
//It configures the period (in seconds) of the BLF subscription for account X.
The IP phone is able to successfully refresh the SUBSCRIBE before expiration of the SUBSCRIBE dialog.
value : Integer from 30 to 2147483647 , default value is 1800//
