Configuring SIP Registration to SIP Proxy

SIP Registration to SIP Proxy Overview

Telcobridges supports registering a SIP NAP to a SIP proxy.

• Registration authenticates TelcoBridges product's IP address with a SIP provider proxy or SBC and this will allow SIP traffic from the Telcobridges product to pass through to that SIP provider.

• Registering with a SIP provider from Tmedia/ProSBC will always take place over SIP trunk.

• SIP trunking enables the end point’s PBX (Private Branch Exchange phone system), Telcobridges product such as Tmedia or ProSBC, to send and receive calls via the Internet.

You must configure SIP Registration with a SIP Proxy (a SIP provider/ITSP) on Telcobridges product if it is required for the reasons mentioned above.

SIP registration to SIP Proxy (NAP) can be configured in the NAP editing page:
