[Asterisk-Users] Asterisk , ISA Firewall/VPN , STUN and other issues

[Wiley E. Siler]

I use my XLite softphone from my Win XP box over VPN to my Cisco PIX
with no issues so this can be done.  
How that works for an ISA box is unknown to me.  I dumped ISA several
years ago do to it's (IMHO) unpredictability and low performance.
Are you using the built in VPN of WinXP or an ISA Client ?
 
Phones are very preferential.  Grandstream and SNOM make some good cheap
phones if presentation is not an issue.
I personally prefer Polycom IP300 and IP500 for ease of use and
features.  IP300 can be had for $135 on eBay.
Some like Cisco though the Cisco licensing model irritates me to no end
and I refuse to use them for anything other than firewall/router at this
time.
 
Cheers,
Wiley

I have just finished compiling and installing Asterisk on a test Debian
system. All is working well. We are now attempting to get remote offices
to test the system I have installed both a SIP and an IAX client at a
remote office. Then I connect to our office via Microsoft ISA firewall
and the Windows XP VPN client. Neither of the softphones will connect.
On the IAX softphone I just get a ringtone , on the SIP client nothing.
The Debian machine has two NIC's , one with a static external IP and one
with an internal IP. Our remote offices are behind a mixture of
firewalls.

 

 

I have some questions with regards to our testing and setup.

 

1)       Is there a way to get the SIP/IAX client to work via the VPN?
This would be the easiest way.

2)       If not can I install a STUN server on the same machine as the *
server? Can it use the same internal and external IP's as the * server?

3)       Is there a hardphone that supports VPN that has been tested?

4)       What is the best hardphone to use with Asterisk?

 

 

Thanks for the input

Shawn Dillon
