Well, since I own or manage the companies... I think it is gonna be OK.

Really, you want a plug-in backdoor into their network that the sysadmin 
doesn't know about... this product isn't designed for low-tweaking use but 
would probably do what you want.  https://www.wired.com/2012/03/pwnie/ . If you 
do the drive out to Las Vegas for DEFCON in a month there's probably more of 
those that you can see in the vendor area.

I can try doing the same myself with a few Mikrotik boxes and a bit of 
scripting, and if successful you can order devices for yourself and I can 
program them remotely (or just send them to me and pay the shipping to yourself 
after).

the phone with me.

  The VPN would rarely ever be software on the server. A bigger factor is that 
most network admins would take a dim view of you asking to install VPN server 
devices that they can't control/update on their networks as that can be a 
massive security risk.

    OK, but at the far end it would be good to have a small piece of hardware 
too rather than depend on VPN software running on some random server.  I would 
rather not bother the various IT folks at these different companies that all 
run asterisk.

      Let’s say I am in a random hotel room and I want to use my Aastra phone 
back to my office asterisk.  

      That is similar to what I need to accomplish.

      Instead of a vpn it might be better to just allow it to connect through 
the firewall (assuming you are able to manage the firewall)

        Other way around, I want to use my Aastra from my home office but I 
want it to connect to two other companies’ business office asterisk systems.

        Hey Chuck,

        What about using a sip client app on your mobile phone?  You can turn 
on vpn on the phone.

        Or do you want an actual desk phone?

          I wonder what the simplest and cheapest method is to use an Aastra 
SIP phone while away from the office.  Our Asterisk is on private IP space so I 
have to have the phone tunnel into my internal LAN.  There are firewall boxes 
available that will do this.
