Not. With geographical aggregation, you may route a call *anywhere* in the destination country.
You mean anywhere in the world. Calls to my number reach my cell phone no matter where I go.
You are confusing number portability and call forwarding.
You're confusing call forwarding with international roaming. Obligatory back story. In the early days of international roaming I had cellular service in the US with AT&T. I traveled to Bulgaria for a week and took my phone with me. International rates were on the order of $3.95 per minute. I deliberately left my phone turned off so as to avoid expensive incoming calls. On arrival I turned my phone on and made two calls to let people at home know I'd arrived. During the trip I would turn it on and make a call occasionally, total under ten calls, all outbound. When I got home I would up with a bill totaling several hundred dollars. Every time someone called my number the call got routed to Bulgaria. The call then went back to the USA and hit my voicemail, so I got charged $3.95 twice for each of these calls. I eventually got the bill resolved, but it took a very long time and multiple escalations. Suffice it to say that AT&T customer service reps are located nowhere near the "A" in "AT&T". A year later I made another international trip. Ahead of time I called AT&T to ask them to disable voicemail so I wouldn't have to deal with that again. I finally was able to do so but that, too, took multiple calls to people very obviously not in "A". -- Jay Hennigan - jay@west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
