Are you inserting a VIA header on the BIGIP? Having the BIGIP insert a VIA header will ensure the server uses the details in the VIA to send the BYE via the BIGIP instead of the UAC/phone directly.

 

If you are already inserting a VIA header on the BIGIP then open a ticket with F5 Support and provide a packet and a qkview taken after the packet capture.

 

Syntax for taking a packet capture will be like below assuming same port is used for vip and pool:

 

tcpdump -ni 0.0:nnn -s0 "((host( or ) and port )" -w /var/tmp/SIP.cap

    We are not inserting VIA header, should i insert VIA? if yes then what would be the option and setting?

    we are just inserting 

    Record-Route
    header.

    also i have created this iRule, reason i created iRule because i have notice my packet was bouncing between F5 and SIP server and adding many many record-route over and over and finally it was dying. 

    when SIP_REQUEST_SEND {
     SIP::header remove "Route"
}
