Callcentric
From Pbxnsip Wiki
Information about the Provider
Callcentric allows individuals and companies worldwide to make and receive phone calls over the internet to each other for free, with no signup or monthly fees. Additional paid rate plans and services are available for worldwide calling and real phone numbers (DID/DDI) starting at as little as $5.00.
How to set up a trunk
The provider will provide you the account number and the password. A typical setup will look like this:
- Display Name: 17772830319
- Account: 17772830319
- Registrar: callcentric.com
- Username: 17772830319
- Password: xyz
- Outbound Proxy: callcentric.com
- Strict RTP Routing: Off
- Ringback: Media
You dont need to specify a STUN server or a keep-alive time, because the ITSP will make sure that the PBX will keep the NAT binding alive (if it is behind NAT).
If you are redirecting calls to the cell phone, you should use the "Remote-Party-ID" indication, so that Callcentric knows what CID it should display.
More Information
Callcentric has a web page describing the setup as well. See http://www.callcentric.com/support/device/pbxnsip for more information.
