VoIP - Calling With a SIP URI
Incoming calls can be made from the internet to your number by using a SIP URI such as:
A call to a URI like this will be delivered just like a normal incoming call.
The format of your number should be in +44 format, eg to call AAISP support you'd use:
- You do need to use the hostname aa.org.uk as we use SRV records to direct the call, so using an IP address is not supported.
- The CLI is not trusted for such calls, so are sent to your SIP handset with a ? on the front, and not passed on if the call is diverted.
- So, for example, without any configuration or account details a softphone may call your A&A provided VoIP number, as shown in the image here.
- As mentioned, this does require the client (the phone you're calling from) to support SRV records.
