I just updated Asterisk from 22.214.171.124 to 11.0.1. Since this update, Asterisk sends a sip notify for new voicemail message each 9 minutes.
If I have one message in my mailbox, the phone play the new message sound each 9 minutes.
I didn’t have this problem with 126.96.36.199
I don’t find any setting in voicemail.conf for that. Anyone have an idea?
