softphone from internet and call manager behind pix

Dear allm

I would like to ask all that we got staff outside office want to use the softphone program from the hotel, and eventually connect to the callmanager which is located at office homevlan.

What we get on hand is the cisco switch , callmanager and pix firewall + 5300 gw.

Is it possible to make it works?

Any document refer to this.

Tks very much.

Re: softphone from internet and call manager behind pix

it is possible to make a softphone work over the internet, through a firewall.

one of the best ways is to use a VPN connection. need to create the softphone in call manager with the MAC address of the NIC in laptop.

without VPN connection, you'll have to open port TCP:2000 (SCCP) and UDP:16384-32768 (RTP) on the firewall (again, i'd go with a VPN to enhance security to your network)
