When I dial 1+905 from a REAL 416 phone, I immediately get the recording "We're sorry, your call cannot be completed as dialled." Right after the 1-905. No more digits required. And this has always been the case, even before 905 and 706 were taken out of service. The old 905 and 706 area codes NEVER worked from Canada; they were special area codes that worked from the U.S. only. I suspect that Tony is calling from a PBX with some sort of smart routing. Apparently his PBX has some lines to some point in the U.S., which it uses for calls to non-Canadian area codes. john

OK, I have revised the bottom of my area-code-history file to read: On February 1, 1991, area codes 706 and 905 (used in the U.S. for calling parts of Mexico) were discontinued. Country code 52 was to be used in their place. This made 706 and 905 available for use elsewhere.

Well don't be *quite* so sure. I have just retried the experiment. When I dial 1 905 555 1212 from my home phone (416 486) I get a message in English and Spanish as I reported previously. It comes from some distance away (judging by the connection time and quality), but it does not now have the 619 identifier on it. The accent in the English part is clearly American. When I dial the same call from my office phone (PBX trunk in 416 492) it gets intercepted at the Toronto toll switch (not at the local CO) with the "cannot complete your call as dialed" message. Since there are quite a few toll switches in Toronto, it seems clear that my home and office COs home on different ones that are programmed differently. My home is served by a #1ESS, while my office PBX trunks are on one of the few remaining crossbar switches in town. Probably your phone is served by a DMS or SP1 switch, both of which have fancier programing capabilities. Tell me your CO prefix and I'll tell you what kind of switch it is. > I suspect that Tony is calling from a PBX with some sort of smart routing. > Apparently his PBX has some lines to some point in the U.S., which it > uses for calls to non-Canadian area codes. Definately not. I am quite familiar with how our PBX is configured and we have no lines to the US. All our US calls go via DDD because our calling volume to the US is very low. If you check a Toronto phone book from just a few years ago you will find 905 documented as the way to reach Mexico City, and country code 52 not listed in the overseas section. Tony H.
