You can also set up multiple physical or vlan(ed) interfaces and bind sip
to one and pjsip to the other - then you have to set up the appropriate
interface routing too for both inbound and outbound packets which takes a
good understanding of your network topology and the locations of your
respective devices. You might be able to do it with multiple addresses on
your interface too (although I haven't tried it).

All of the packets have to be presented to the appropriate channel
otherwise get discarded. You can't set it up so if a packet is from a
device not registered with pjsip, it gets passed to chan_sip to try.

For me, I had both channel types running on production machines while I
migrated to pjsip or when not being able to figure out how to set up some
property in pjsip that you had running in sip. Each time I've had to do
this, eventually I was able get it all running within pjsip. I also already
had multiple vlans configured for my servers (with voip exclusive to one).

The short story is that it is easier to learn how to get things working
within pjsip than learning the tricky networking setup.
