Media is not flowing, auto hangup after 6 seconds and getting retrans_pkt: Retransmission timeout reached on transmission rkgm4q2qj1c1u8ogh1dt for seqno 784 (Critical Response) [all are connected locally]

Hi,

I am almost new on sip and am trying to do communication through webrtc with sip. I am developing this on nodejs platform using sip.js.

From web application, ext 202 is calling ext 201 (on zoiper) and all extensions are in sip.conf. Everytime I am getting incoming call and can answer the call. But after 6 seconds its gone automatically with no media. Here my web, webrtc (kurento) is on one local vm and the sip one is on another local vm and they are connected locally through LAN.

I paste the log here in below. Please help me
