A SIP Trunk allows you to route multiple calls over the Internet to an IP capable PBX system. 2talk uses the SIP protocol to deliver calls to your PBX platform. If you do not have a SIP capable IP PBX, a SIP/ISDN Gateway or a VoIP Gateway then you should not use the 2talk SIP trunking service.
SIP Trunking can be seen as a low cost replacement for traditional PRI or analog circuits - using the Internet to make/receive calls instead. This means cost savings for you the customer since you do not need to order expensive circuits from your telecommunications provider and can use your existing broadband connection to terminate/place calls instead.
What do I need to setup 2talk SIP trunking?
- A static Internet (IP) Address. Dynamic DNS hostnames are not allowed. 2talk SIP Trunks use SIP Peering as the connection method which means you need to have a static IP address to be able to use our SIP Trunking solution. If you are not using 2talk Broadband you will also need a public IP address.
- No firewall rules or NAT blocking traffic between 2talk's servers and your IP-PBX/Gateway. You may setup firewall rules to limit traffic to 2talk's servers or setup port forwarding if required for security reasons.
- You need a SIP (v2) compatible PBX platform or gateway. 2talk does not support H.323 or other VoIP protocols.
If you are unsure whether your IP-PBX is compatible with 2talk then contact firstname.lastname@example.org for more information.
