The problem with packet loss was that in case the network goes down the packet loss still shows 0, and after it comes back it starts reflecting packet loss even when the call is connected with great call quality. Even RTT is inconclusive, jitter seems like the best bet. Thanks for the tip though, have to still optimise for edge. -- Vinay Nair vinay.nair at novanet.net On 31-Jan-2014, at 5:42 pm, pjsip-request at lists.pjsip.org wrote: > Send pjsip mailing list submissions to > pjsip at lists.pjsip.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > or, via email, send a message with subject or body 'help' to > pjsip-request at lists.pjsip.org > > You can reach the person managing the list at > pjsip-owner at lists.pjsip.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of pjsip digest..." > > > Today's Topics: > > 1.
