| Description: | We are getting ready to make the jump from v1.8 to v11.6-cert4. One of the new features (as listed in https://wiki.asterisk.org/wiki/display/AST/Upgrading+to+Asterisk+11) we were most excited for was the new unique msg_id column in the voicemessages table. The hope was that this would allow us to store additional information related to a message.
However, it appears that the msg_id value changes whenever the message is moved to a different mailbox (i.e. moved from INBOX to Old). Is this expected behavior or is it a bug? | ||
| Comments: | By: Steven Wheeler (swheeler) 2014-07-02 13:37:19.104-0500 Here are all the SQL queries which are executed by app_voicemail when checking a new voicemail and moving it from INBOX to Old. You can see on line 16 that the message is being copied from INBOX to Old, but a new msg_id was generated. And then on line 18 the original message is deleted. By: Michael L. Young (elguero) 2014-07-03 16:20:33.523-0500 It would appear to be intentional. https://reviewboard.asterisk.org/r/2220/ Anytime a message is copied, it will receive a new msg_id. If you read the comments on the code review at the link above, you will see why it was done this way. By: Steven Wheeler (swheeler) 2014-07-03 16:31:30.644-0500 Michael, Thanks for following up on this. From looking at the source code yesterday I kind of figured this was the case. If we can't rely on the msg_id to be a fixed value what purpose does it serve? Why was it added? By: Michael L. Young (elguero) 2014-07-03 19:07:01.999-0500 One thing that comes to mind would be that msgnum could change but msg_id stays the same. The msg_id only changes when a new record is made in the database. The new record is created when moving a message to another folder or when listening to a message. When listening, the record is automatically created in order to put the message in the Old folder. Otherwise, as long as you are not copying the message around, the msg_id stays the same, even if you delete or add other messages to the same folder. | ||
