Re: multihoming & BYEs

John,

This reply probably isn't going to be helpful, since I obviously misread
your entire email. For some reason I was thinking enable_double_rr, so I
set:

modparam("rr", "enable_double_rr", 2)

And tried again, same issue.

Sergey asked for the SIP messages. I didn't want to spam the list, so I put
them at https://fdf.net/calls.txt

It's late now, I'll try record_route_preset in the morning and try again. 🤦

Thanks!
