And after 303 tries to call 302 while 301 & 302 are still on a call (301 & 302 on a call, plus 303 calling 302):

_3XX@hints : Custom:${EXTEN} State:Idle Watchers 0

302@hints : Custom:302 State:InUse&Ringing Watchers 2

303@hints               : Custom:303 State:InUse           Watchers  2

301@hints               : Custom:301 State:InUse           Watchers  2

But despite the above, the BLF fields on my phones (Cisco SPA 509G for all 3 extensions) only update for Idle or InUse -- they do not show the Ringing or InUse&Ringing statuses. I have verified the SPA phones BLFs do still show the correct Ringing and InUse&Ringing statuses if they subscribe directly to a SIP device's state with the hint -- the issue only seems to be effecting Custom devices. Can anyone think of anything else I should check?


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.
