Description:	I have run some tests by subscribing to voicemail with 2 phones (Polycom and Aastra). In both cases asterisk do not terminate voicemail subscription when it receives the 481 code from the phone.Since the phone subscribe to voicemail after each reboot, subscription are piling up in astdb and asterisk keep sending multiple notify to the phones. My pcap from both phones proves it. Am I missing something ? I understand that subscription persist but why is asterisk keep sending multiple notify even after receiving 481 from the phone? I have checked in astdb and subscription are never deleted either.

Please follow the instructions on the wiki [1] for how to collect debugging information from Asterisk. For expediency, where possible, attach the debug with a '.txt' file extension so that the debug will be usable for further analysis. Thanks! [1] https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information By: Rusty Newton (rnewton) 2017-01-29 15:15:14.640-0600 See the previous comment and link to documentation. Grab an Asterisk log that includes the PJSIP logger output, along with warning,error,notice,verbose,debug log levels. Make sure that verbose and debug log levels are both turned up to a verbosity of 5. By: Rusty Newton (rnewton) 2017-01-29 15:15:56.713-0600 In addition please include the PJSIP configuration (.conf or database dump, or CLI output) for each endpoint. By: Carl Fortin (phonefxg) 2017-01-30 06:40:11.792-0600 This is what I have collected when calling the endpoint twice and leaving 2 messages in voicemail. You can clearly see that asterisk is sending 2 notify even after receiving a 481 from the first time I have left a message. Debug and verbose set to 5 as well as logger on. I have also included all my conf files and endpoint configuration.
