Configuring the PAP2v2 for CIA (3web)

First, obtain the SIP credentials for your CIA account as described here.

Connect the power, an Ethernet cable to your router and a phone to Line 1. Find out the adapter's IP address from your router's DHCP list (see some samples for different router brands here), then open a web browser (Internet Explorer) and type in that address. The default username is admin and the password is admin.



Click Voice from the top menu to get into the VoIP settings section.



Now click Admin Login on the right then Switch to Advanced view in the middle, to get access to Advanced VoIP settings pages.



Now you're ready to configure the VoIP settings. First, we'll adjust some of the SIP parameters, so click the SIP submenu.



Change the following parameters:

- RTP Packet Size: 0.020

- Handle VIA rport: Yes
- Insert VIA received: Yes
- Insert VIA rport: Yes
- Insert VIA rport: Yes

Now click the Line 1 submenu



Enter the following settings:
