Dialing a SIP URL Call
If you are having trouble registering a line, it is possible to test that the SoundStructure VoIP Interface is
installed properly, except for the line registration, by dialing a SIP URL call to another SIP device. To dial a
SIP URL call:
1 From the Phone Settings Menu, select New Call and then press URL.
2 Click in the Dialed digits area as shown below and enter the URL to dial using your PC keyboard.
For the 'dot' in between the IP address octets, use the '.' on your keyboard.
The remote endpoint can be a desktop phone or the IP address of a different SoundStructure VoIP
Interface being installed. Once the IP address has been entered, click Send as shown next.
