Can you stop RST from being sent by VIP
I work for a large regional public transportation company. We are in the beginning process of rolling out phones with a VoIP over the top application on them. This will eliminate the need for radios (radio transmittion towers are now very expensive). I have determined that, for whatever reason, these phones send a DNS request on TCP port 853 and with that the VIP sends an RST to the requesting phone. That in turn resets the connection, the VoIP app beeps, disconnects for 30 sends, and then reconnects.
I have both the phone and app vendor looking at this but thought I would see what it would take to mask this problem from the F5 side. I do realize that all DNS traffic currently hits this VIP, so at this time I am only exploring my options.
