The next job is to create a SIP endpoint, as this is how your Asterisk will connect with SignalWire.

From here on in, you are working within your project. Incidentally, a single US DID costs just 8 cents per month! SIP connectivity is metered per minute/per call leg at just $0.0007, and that includes SRTP and TLS encryption that many providers charge extra for.Īs you create your account, you create a “Space URL”, effectively the subdomain at for your account. This is very easy and straightforward, and you are even given a $5.00 credit to do things like buy DID numbers. The first thing to do is to go to and create a SignalWire account. Now it’s true that SignalWire is massively more than just competitively priced SIP trunking, but seeing as I already know Asterisk I thought that this would be a great place for me to start!

Having recently started working with SignalWire, I was very keen to see if I could get Asterisk connected up – as just one of the things that SignalWire can do is act as a SIP trunk, providing inbound and outbound calling for your PBX or hosted PBX infrastructure.
