I'd do a packet capture -- ideally from the phone, or using your switch 
to mirror the phone's port -- and look for a SIP NOTIFY. Then we can 
know if a NOTIFY is not being sent, or if it's just not being processed 
as desired by your Cisco SPA 509G. If it's not there, do the same on 
your asterisk server, and if we see it on the asterisk server but not at 
the endpoint, we can suspect network configuration.

You can also get some more detail about what endpoints are subscribed 
with "sip show subscriptions" in the asterisk console, but since it says 
"Watchers 2", that suggests the subscription has been made. I'd just 
verify that specifically the device you are using for testing is subscribed.

Also, I know if you turn the verbosity up high enough (core set 
verbosity 3) you will get messages in the console about notifications 
sent. You can also "set sip debug on" or something along those lines and 
have Asterisk print all the SIP traffic it's attempting to send. Should 
help you narrow the possible causes.
