[SR-Users] BLFs are not working

Sun Oct 3 06:32:19 CEST 2021

So, it now seems confirmed..

Grandstream GXP1782 FW 1.0.1.116 does not work with the NOTIFY process of Kamailio 5.4.4

Grandstream GXP1782 FW 1.0.1.119 DOES...

On review of the Grandstream 1.0.1.118 update, • Fixed BLFs are not updating sometimes when using certain SIP servers

So, there ya go...
