DNS-SRV Registered Phones to Not Respond to Options Messages
I am experiencing a bug with all Yealink phones, where if I use a DNS-SRV address as the registrar, they do not respond to SIP OPTIONS messages to keep the NAT pinhole open. If I switch back to UDP, they respond normally.

When I do a PCAP on the yealink phone itself, I can see that the phone gets the packet, bt it does not respond.

Is there anything we can do to get that working?
