[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=233524#comment-233524 ] 

Joshua Colp commented on ASTERISK-26548:
----------------------------------------

There is no mechanism currently to limit the number of subscriptions and they will exist until they expire, or until a NOTIFY receives a fatal response. Other phones will respond with a 481 Call/Transaction Does Not Exist to the other NOTIFY messages causing them to be terminated.

> We are using the mailboxes in the AOR table so our Cisco phones can subscribe to Message Waiting Indications.
> Once in a while the light would not be on even with new messages, so I did a trace with wireshark and found something weird.
> The phone boots and subscribe sucessfully to MWI with a voicemail subscribe interval of 86400.
> If I look at my wireshark trace I can see that asterisk sends a sollicited notify 5 times. Is this normal?
> I have also noticed that the Subscription state is going from 83544 seconds to 432 seconds and it expires in the last notify.
