[asterisk-bugs] [JIRA] Commented: (ASTERISK-20295) Asterisk is not incrementing the sequence numbers for the retransmission of the DTMF end packets(RTPEvent packet with end bit set to 1)

[Mark Michelson (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-20295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=196425#comment-196425 ] 

Mark Michelson commented on ASTERISK-20295:
-------------------------------------------

Okay, if 1.4 and 1.6.1 and 1.6.2 had this behavior, I'm willing to change it in 1.8 forward without the need for an option. I'll do a review of Michael's patch on review board today.

> Issue: 
> All 3 retransmitted ending packets share the same sequence number, which does not comply with RFC 4733 Sect. 2.5.1.6. RTP Sequence Number
> The RTP sequence number MUST be incremented by one in each successive RTP packet sent. Incrementing applies to retransmitted as well as
> initial instances of event reports, to permit the receiver to detect lost packets for RTP Control Protocol (RTCP) receiver reports.
