Enswitch SIP Trunking

Creating a SIP trunk with Enswitch can be done, as follows.

Outbound calls

• The remote device can register as a normal telephone line. If the telephone line has caller ID set to "Original" then Enswitch will pass whatever the remote device sets as the caller ID.
• You can set up a Remote Access account to allow calls from a fixed IP address. You need to set the type to "Dial the called number" and enter the source IP address. This means the remote device does not have to register with Enswitch to make outbound calls.

Inbound calls

• If you're happy with having one destination number on the remote device, you can route a normal number to the telephone line the remote system registers with.
• You can create multiple numbers routing to the same telephone line, and then set the telephone line option "Send called number as request URI" to Yes. This will send the call to <dialled number>@<telephone line registered IP address>.
• If the remote device is not registered as a telephone line, you can send calls to a fixed address using the SIP URI destination type.
