6 thoughts on - Asterisk And Maybe A Freepbx Question

• They can’t. One application per address/port pair.

  You can configure pjsip to bind to another address and/or port while you figure it out the configuration.

• Hm, which version of FreePBX uses Asterisk 18.3?

  They can’t.

  One might be on TCP and the other on UDP, but you can’t have them both listening on the same port with the same protocol.

  What makes you think chan_sip and pjsip are both listening on UDP 5060?

  As far as I recall using FreePBX, there is a selector for the SIP protocol to tell it whether you want it to use pjsip or chan_sip. I don’t think it even supports using both at the same time, so simply make sure that is set to chan_sip and you should be fine.

  On the other hand, why do you need to learn “how to configure the thing” if you’re using FreePBX? Part of the whole point is that it does the fiddly techie sutff in the background for you, and you just need to use the personnel-
  department-friendly web GUI.

• This is what I thought as well, I just generated one trunk using the old chan_sip and expected nothing from pjsit, yet I get all kinds of errors like
  [2022-01-08 17:08:59] WARNING[487628] res_pjsip_registrar.c: Endpoint
  ‘anonymous’ (45.134.144.118:5823) has no configured AORs

  so I am very confused as to why this is happening.

• In freepbx you enable chan sip or pjsip or both and set what ports they use

  The choices are either in advanced settings or sip settings

  Disable pjsip and reset the chan_sip port to 5060 or use pjsip. With them both enabled sometimes odd things happen but it will still work. You will get lots of error messages though

• 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.

• OK, that tells me something, I will disable pjsit for now, learn about it and try again.
