Summary: Call abort after wrong behaviour of VNAK
transmission
Description:
Asterisk sends VNAK to signal a retransmission of a packet. After
retransmission the request is sent again and again... Abort of the call is
the result after a few retries.
Overall, asterisk very often sends VNAK after receiving LAGRQ and PING
consecutively. Why does asterisk know that packet 2 after 1 is missing if
there was no packet 3 so far (numbers referring to ascending sequence
numbers in IAX Header)? This is confusing since the RFC states the below
text requiring to retransmit all frames with a higher sequence number than
the one received with the VNAK.
Please see the attached pcap file.
There was no significant output in the asterisk console, so I do not post
this as of now. If required I can post this later.
