Hello!

Please help. BLF is not working at my T26P at all. Earlier BLF worked fine until I updated new firmware on the phone. Now, doesn't matter which version of firmware I'm trying to use - update can't help (I tried to use from 6.71.x.x to 6.73.x.x).

When phone trying to send a SUBSCRIBE request, server always answers "Bad Event".

1. Please tell me the detail firmware. You can try to upgrade to the version below and reset the phone then test again.

2. If upgrade and reset can't fix the problem, please help us to get the pcap and syslog files, we can check something from them.

Thank you very much! As usual, blame inattention.
