      Issue is resolved after enabling "rtp-rewrite-timestamps" on sip_profile
      https://wiki.freeswitch.org/wiki/RTP_Issues

      Probable also may be fixed if quepmnet local clock will be syncronized via ntp protocol.
      Additinational info will be late

      FS server receive answer from b-leg, but is pass media from b-leg to a-leg with very large delay. Delayed media packets is drop on a-leg side.

      When opened pcap file in Wireshark and select "Telephone" -> "RTP" -> "Show All streams". Then select stream from "91.103.196.11" - "217.12.246.114" -> "Analyze" -> select packet #324. From packet 324 and below "filtered jitt" field value is large then "ptime" value.
