[Peter Jamieson (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-24495?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=223287#comment-223287 ] 

Peter Jamieson commented on ASTERISK-24495:
-------------------------------------------

I did wonder if that was the reason, but the comment in sip.conf says: -
{noformat}
ignoresdpversion=yes           ; By default, Asterisk will honor the session version
                                ; number in SDP packets and will only modify the SDP
                                ; session if the version number changes. This option will
                                ; force asterisk to ignore the SDP session version number
                                ; and treat all SDP data as new data.  This is required
                                ; for devices that send us non standard SDP packets
                                ; (observed with Microsoft OCS). By default this option is
                                ; off.
{noformat}

Note that is says "changes", not "increases".

However, the RFC clarifies that it should be increasing, so i'll look at what is setting it.

> When i send a re-invite back to asterisk with a new RTP port, it is not changing the stream.  I can get around it by setting ignoresdpversion=yes, but i believe that the version number is not the same and it should be changing it anyway.
