Interesting ports on localhost (127.0.0.1): Calls fail with SIP error 503, I-SUP errors 34 or 38: If our platform replies back with 503 it usually means the gateway trying to process the call cant. I have SJPhone and Counterpaths (X-Ten) X-lite 3.0. Warning: Hostname localhost resolves to 2 IPs. Now, that I've learned a little more about IP Telephony/VoIP I've started playing around with some softphones. This opens the SIP Account Settings page from where the phone can be configured to connect to the Natterbox service. Click on Account Settings (this can also be accessed in the Softphone dropdown menu). Go to Account Settings message is displayed. I ran an nmap on localhost and found the following blaine :: /etc/asterisk » nmap localhost When first opening X-Lite, the Account is not enabled. The system status page of the FreePBX admin tool is a good place to start. System details: blaine :: /etc/asterisk » uname -a 503 is 'Service unavailable', so make sure the server-side is up and operating normally. I'm just trying to get Asterisk to work with a basic setup so I can experiment with it. When I add an account it says Could not register I've also tried setting the registrar in Ekiga to 127.0.0.1. My Asterisk server is running on my desktop, as well as my softphone (Ekiga). I'm up to the point where I've configured sip.conf and nf according to the book.Įxten => s,1,Verbose(1|Unrouted call handler)Įxten => 500,1,Verbose(1|Echo test application) I'm familiarizing myself with Asterisk, and I'm reading the book "Asterisk: The Future of Telephony."
