Hello. I use kamailio with last rtpengine and I have 5-7 Seconds voice delay. This happened only for from webphone. But it is not client issue as i see. Wireshark at client side shows that RTP starts as soon I pick up call. So rtp leaves rtpengine and goes to the destination with delay... I use WSS and think that problem at handshake.
There are some statisticcs after call finished (as example). You may see that one of streams created after 5 seconds delay.
