<div dir="ltr"><div>TLDR; Global routing is getting messier and messier. Get a few carriers in route for intl calls. Anything other than a BUSY should fail to the next carrier in route.</div><div><br></div>Global routing has been a cluster **** as of lately. Two issues have risen as of late. The first is countries cracking down on spam traffic. Lots of countries (Australia, UK etc.) are forcing carriers to watch the traffic coming in a lot closer. The second is the rates. A few years back the EEA put in regulation that inter EEA calls need to be charged the same low rates. The carriers started a two tier billing system. If the CLI was in the EEA it was the lower rate and if the CLI was non EEA it was billed at a higher rate, there were some exceptions. This set off a chain reaction. South Africa was next. Wholesale was about 0.025 per minute for Mobile. Overnight inter SA calls were charged the same while calls from outside SA were charged at 0.16 per minute. In SA they were more strict and spoofing CLI didn't help. It took about 1-2 years for the routes to stabilize. Tier1 carriers had GSM gateways in route (we proved this by using iTest). Carrier started spoofing CLI to EEA countries with a local number (e.g. if they called Germany they made up a number that started with 49). This led the German carriers to charge a higher rate if calls to Germany came with a local CLI (it's still cheaper if the CLI is from another EEA Country). The Israeli carriers recently started charging an extra 0.10 per minute if the calls come from out of the country. This led the UK carriers to raise their rates. Where the CLI to UK calls is Israeli, they started charging 0.30 per minute. Currently BICS has more route exceptions for pricing than they do have actual routes. There is a lot more here and I can talk for hours on the subject.<br><br>Carriers want to advertise/offer the best route to win your business. So say Cyprus cost 0.10 per minute for non EEA CLI, if a carrier has a GSM gateway option that costs them 0.02 per minute they will issue you a rate of say 0.3 per minute and if the GW is busy simply reject your calls. This they they win whatever traffic you have going to them based on your A-Z routing. I would tell you to look at:<br>Voxbeam<div>IDT (Net2Phone) - Ask them for their platinum rate deck, I would not go any lower.</div><div><br></div><div>My 9-5 is the equiv of a CLEC in Cyprus and our "specialty" is getting good quality routes. If the others don't work free to email me off list and I can try to help out.</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Jul 13, 2023 at 3:34 PM Ross Tajvar via VoiceOps <<a href="mailto:voiceops@voiceops.org">voiceops@voiceops.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi all,<div><br></div><div>I have an asterisk PBX for personal/business use.
