Your point about 112 is very useful but slightly misguided; although the UK has used 999, nationally since 1938, (the world's first single number access for emergency services) 112 was mandated for pan European use from 1992 onwards. 112 is *not* for "foreigners who don't know any better", it's for everyone in the EU to learn so that when you are anywhere in the EU you stand a fighting chance of getting hold of emergency help at the first attempt. 999 will continue to run in parallel with 112 for many years to come but 112 should be taught to children and adults alike as the universal number for emergency services. Some UK Telcos also provided support for 911 for a little while but I believe that this was officially frowned upon; I'm not sure what the policy is now.

It became apparent, back in 1999, when I was part of a team providing consultancy to a UK Telco for VoIP VPN launch, that a POTS line would be required locally at each branch office for power-fail compliance and to ensure that the OACs (Operator Assistance Centres) did not get confused about which location the emergency call was originated from. We discussed spoofing the branch office CLI "in network" at an SS7 level but that idea was shelved as there would have to have been an associated POTS line entry in the OAC database in the first place. At that time Cisco CPE had no way of utilising the power-fail POTS lines so a red 'phone was provided for use on each floor of the branch offices that only had VoIP VPN telephony.

You can watch the log and see that the call attempted to route to the POTS line. You can then dial a "real" POTS number and watch the same route succeed. The emergency services get very upset if you call them to test, unless you've arranged to do so in advance and have an allotted time slot. You're right though; you can't be absolutely sure that the 999 route will work until you test it with a real call. Just start a fire before you call. That'll probably work. :-) > > As another thing, what is the correct method when using least cost > routing...

The emergency services tend to rush to the destination they "know" is correct for that phone number. By the way, it's useful to map 911 and 112 onto your 999 route for the benefit of foreigners who don't know any better. -- _/ _/ _/_/_/_/ _/ _/ _/_/_/ _/ _/ _/_/_/ _/_/ _/ _/ _/ _/_/ _/ K e v i n W a l s h _/ _/ _/ _/ _/ _/ _/ _/_/ [EMAIL PROTECTED] _/ _/ _/_/_/_/ _/ _/_/_/ _/ _/ _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
