HELP => Installing SIPs on local network, 666, WOT

Asterisk Asterisk Support

Is it possible to set up and use SIPs on a local network? Soft phones and the Asterisk Server.

On the soft phone (X-Lite) running on Win XP I get an error message:

Registration error 408 - Request Timeout

The soft phone never gets registered. Can any one help?

Is 172.16.0.14 your server address? Why do you affix port number to a domain?

Many Thanks for your reply

You are right. The SIP proxy is apended with the port number.

I will try out your suggestion tomorrow when I am in the office.

Yes, the internal IP of the Asterisk machine is 173.16.0.14.

I tried the above with no luck.

However, when I installed the softphone on the asterisk machine the softphone registered.

X-Lite Soft Phone Settings

Display name Welby
Username 6001
Password welcomme
Authorization User Name 6001
Domain/Realm 172.16.0.14
SIP Proxy 172.16.0.14:5060

Outgoing call: I could reach an internal extension => a physical phone. The softphone wouldn’t accept incoming calls.

The softphone does not register from another machine on the same internal network? Why?

HELP

Tony

ps. Many thanks for the help received to date.

One usual suspect is host firewall. Which distro are you using? I suspect RedHat/CentOS. For your initial testing, completely disable all firewall.

The firewall => Never occurred to me. Seems obvious now.

I will try it tomorrow.

I am using Fedora Core 6 with open source Asterisk. I am also using Lumenvox and NeoSpeech.

Again, many thanks.

Amarjit

Ps. I will post the outcome here.

Thanks Valley.

Switching off the Firewall solved the problem. I am now moving onto to configuring the Asterisk machine.

I am in the process of setting up the soft phones and testing them.

Many Thanks

Tony
