I currently have my Polycom 650 phone set up with presence enabled:

<feature feature.1.name="presence" feature.1.enabled="1" />

However, when I looked at the table sip_presence in sofia_reg_internal.db, I do not see any information in there.

What I am trying to achieve is something similar to "sip show subscription" to verify BLF subscriptions.

Is there something that I am missing here.  Please advise.

Thank you.
