Enswitch SIP Trunking

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

Outbound calls

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

Inbound calls

• If you're happy with having one destination number, you can just 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>.
• You can create multiple Numbers and set the destination type to be a fixed SIP URI address, with a different address for each user on the remote system.
