[asterisk-users] SIP, Polycom, Asterisk - VPN

[Danny Nicholas]

IAX uses one port; SIP uses 2-4 per call.  We use Polycom 550's to talk to
an Asterisk 10.X box.  Nothing special on the Asterisk side; just have to
get your VPN to talk to the Asterisk network.

Thanks for the reply!

 

Why IAX over SIP?

 

In what environment/setup are you using a VPN for the phones?

The "easiest" way to accomplish this is probably going to be to set up an
asterisk server in the remote office and just use IAX to talk between the
two boxes. We do VPN here for two phones but I can't really tell you all
that you need to know.

I am trying to configure the following scenario but have failed.

 

Currently, I have an Asterisk box sitting on a Static Public IP address in
my office.

 

I have a remote office with 3 Polycom IP335s that are registering back to my
local office's publically address Asterisk box.

 

The remote office Polycom phones are getting IP information from an RV042
and using the local ISP for internet access.

 

I want to set up a VPN on the remote side.

 

Has anyone done this? Does it make sense to do this?

 

Thanks,

--E
