             Summary: Mutliple SIP NOTIFIES at 'sip reload' if mailbox is monitored by multiple sip peers
                 Key: ASTERISK-22086
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22086
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_voicemail, Channels/chan_sip/General
    Affects Versions: 1.8.22.0
            Reporter: mdu113
            Severity: Minor


If VM box is monitored by multiple sip peers then asterisk will send multiple SIP notifies about this mailbox to each peer at "sip reload". If number of peers monitoring the mailbox is N then the number of notifies asterisk sends to each peer is N+1. Total number of notifies = N*(N+1).
This will happen only if "pollmailboxes=yes" is present in voicemail.conf.

The relevant parts of configs are follows:

voicemail.conf:
pollmailboxes=yes

sip.conf:
[poly_650_01]
type=friend
context=xyz
host=dynamic
mailbox=650 at xyz 

[poly_650_02]
type=friend
context=xyz
host=dynamic
mailbox=650 at xyz 

[poly_650_03]
type=friend
context=xyz
host=dynamic
mailbox=650 at xyz 

With this config 12 notifies about 650 at xyz is sent. This results in storm of notifies if any significant number of peers are monitoring a mailbox and is just obviously wrong.
