>         Environment: OS: Debian squeeze distribution x86_64 architecture
>            Reporter: NITESH BANSAL

> 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.
