Teleworker without MBG

Do they require a Deskphone or happy with a softphone?
I have also configured a SIP softphone (many free ones out there) on a PC that has a VPN to the office network. That will get past the firewall issue but it does affect the audio if the bandwidth is not good.
This is more a networking question than a phone one to be honest.

I think a softphone will suffice.  They can get a vpn on the pc to run.  So a softphone would work that way.  do you just configure it as a sip device to the controller, and let them pass it by the firewall?

johnp:
Yes would be a generic sip, vpn would need to tunnel both the connected network and the phone network on the user end, would assume local vpn connection would take care of the route back assuming this is on their firewall.

There are many ways to provide protection such as limiting the access to specific IPs, using TLS etc.

I don't know what f/w they have in place, but a f/w that can also do SBC functionality is a pretty major piece of gear, and expensive. Wouldn't expect a company with one of those to balk at the very low cost of an MBG with a single teleworker license.

If you use TLS, which is recommended, then your f/w must be a proper back-to-back (B2B) user agent (either sip or minet) in order to manipulate the signalling.. and, generally speaking, they also perform user auth.

Allowing TLS through to the call server isn't going to provide any additional security.

VPN on PC is connected to VPN server in corp f/w.. just like any other VPN used to access the corporate network.. Softphone would just be pointed to the mivb, just as if you were in the office. That would work.
