#37 closed enhancement (fixed)

RTCP discard statistic should be increased when invalid RTP packet is received

Some application uses the RTCP RX statistic to detect whether remote call has disappeared, i.e. when no packet is received for some time then application assumes that remote call has gone missing.

Some user agents (X-Lite in this case) send a one byte packet when the call is on-hold to keep the call running. So the receipt of such packet can be used to prevent application from deleting the call.

Unfortunately, this one byte packet will not count on any RX statistic since it was not an RTP packet, so it doesn't pass the rtp_decode() function.

The correct behavior (probably) is to count this invalid RTP packets as the discarded packets.
