Dialling 111 from SIP/VOIP based telephony system

[NYCCGaz]

Morning All,

We have come across an issue and i wondered if anyone has any ideas where to go with it.
We use VOIP over SIP and as a result our outbound cli is from our central location where out Telephony System is based.
However we have sites in various other towns and as such various other area codes.
The problem is when our users dial 111 and ask from say an Emergency Doctor - they are being told they are dialling from the wrong area and are unable to help.

Has anyone come across this issue.

Apparently the 111 servcie are unable to "transfer" a call to the correct areas service.

The way we deal with this is to install local phone line(s) and route emergency calls over it. This way, the authorities get a local number and can see the correct address to send their services to. An FXO/FXS card in the router will allow you to add one or two, or more lines like this.

Welcome to the age of VoIP where nobody knows where you are and in an emergency the ambulance looks for you 500 km away.

This is the same issue with 911 every time there are only IP sets in a place and they hag on a system far away. You need to customize these solutions to make things work properly.

I have never even heard of 111 calls but the same principle as the 911 I guess.
