I've changed my Cisco 7960 firmware to SIP. Also I've configured my phone to call with VoipBuster, but it don't work.
When I turn on my phone, the settings will be downloaded from my TFTP-server. When I go to my SIP configuraton, I see the right Proxy, port, username and password, but in my main screen I see in the top (corner) "VOIPBUSTER SIP" with a phone icon. But in that phone icon, there is a "X". When I try to dial a phone number, the phone say:
To: 0031600000000 (Phone number)
Calling (out INV)
After 180 seconds (i think) the phone says: Reorder.
What do I wrong?
