Description:I have a GXP-2000 with firmware 1.0.1.13 supporting BLFs.
If I register the BLF and I do a "show hints" from the CLI I get:
   -= Registered Asterisk Dial Plan Hints =-
  17                  : SIP/soa-17            State:Unavailable     Watchers  0
  16                  : SIP/soa-16            State:Idle            Watchers  3
Each time I reset the phone, the watchers grows, even if I'm always the only phone to use BLF (in the example watchers are 3 because I resetted 3 times).

I don't know if this can lead to memory leak or some perfomance problems of any kind but I tought it would useful to report.

GREAT thing BLF, btw :D

Please show us the output of 'sip show subscriptions' when your system is in this state.

Also show us a SIP debug of the phone sending SUBSCRIBE requests to Asterisk... the Expires header in those requests will determine when Asterisk decides to close out the subscriptions.

Have you gotten the information that was requested?

We need this in order to help you.

When you reset the phone, it will add subscriptions to "sip show subscriptions". After some time, the subscriptions should expire and the number of watchers should be fewer.

I'll wait to check if the subscriptions expire.
In the meantime this is the relevant (I hope) section of debug:

Ok, after a few hours watchers expires.
I think this bug can be closed then...

Thanks,
Alex
