I need to get working a Softphone behind a firewall

Posts: 3 · New Forum Member Joined: Mar 24, 2006 Posts: 3

I have installed X-Lite as my softphone and it does not work behind a firewall. I MUST get a softphone working behind a firewall.

Skype has a feature to configure Skype to work behind a wifewall and it works. Now I need to get this SIP Softphone to work.

Maybe I must tunnel the softphone or use other software to get it working behind a firewall. Please help!!!

Does anyone know how to achieve this? Must I use another SIP Client? If so, what software? OR Must I tunnel my SIP Client? Any recomendation for a HTTPS-tunneling-client?

Please help!

Sincerely,
Justin

Since this is on a machine, you'd have to configure the software firewall (or the hardware firewall too). but you need to open certain ports in order for the softphone to hit the vonage servers.

Quote:

The following ports are needed for OUTGOING Internet communications from the Vonage device to the Vonage servers.

DNS: Port 53 UDP

TFTP: Port 21, 69, 2400 UDP

HTTP: Port 80 UDP

NTP: Port 123 UDP

SIP: Port 5061 UDP (used for older Vonage devices provisioned before 2005)

The following ports are needed for INCOMING and OUTGOING Internet communications from and to Vonage devices and servers.

RTP (Voice) Traffic: Ports 10000-20000 UDP. When a call is made, a random port between 10000 and 20000 is used for RTP (Voice) traffic. If any of these ports are blocked, you may experience one way or no audio.
