Hi Olle,

Yes, I've read this paragraph before posting and to be honest, I couldn't
see any obvious relation with my issue as in my case, BLF are not fully
broken : BLF are blinking, on and off as usual, and pressing a blinking BLF
generates an INVITE.

The only change I saw, is that with 1.6.1, when Asterisk receives a
BLF-generated INVITE *8142, it enters appropriate context and extension and
now, with 1.6.2, it doesn't though it still accept hand-typed *8142
sequence.

I'll dig deeper as obviously, there must be a difference somewhere between
both INVITEs (the one when typing a *8142 sequence and the one generated
when pressing a blinking BLF).
