I have seen this time and time again and it typically is 1 of 2 things that cause this problem... Either the buyers gear or the sellers gear is dropping calls for a variety of reasons...
However "missed a bye" is a pretty poor excuse for the situation... BYEs are acknowledged... And resent a number of times... Even if you did miss 1 BYE message, I doubt you missed 6 or 8 of them as the end terminating the call would resend them repeatedly until it gave up... A perfect example of how this can happen is where an ITSP is trying to route all their calls via asterisk and some telemarketer signs up and dropps 1000 calls/sec on them. Asterisk is not designed to handle this kind of volume. (There are people out there that will claim this but I challenge them to publish a document with verifiable results) So you end up with a hung (deadlocked) or crashed system that eventually is reset and you just lost who knows how many calls and how many CDRs leaving you no good way to bill for the time or validate your bill from the upstream carrier. And this is not just an Asterisk issue this is any switching solution that gets overloaded be it asterisk, coppercom, nextone or even Sonus. (altho most of those guys have some radius based nibble billing so they atleast don't loose a full CDR) K > From: Nitzan Kon <nk3...@yahoo.com> > Reply-To: <nk3...@yahoo.com>, Commercial and Business-Oriented Asterisk > Discussion <asterisk-biz@lists.digium.com> > Date: Sun, 4 Jan 2009 21:02:45 -0800 (PST) > To: Commercial and Business-Oriented Asterisk Discussion > <asterisk-biz@lists.digium.com> > Subject: Re: [asterisk-biz] Experimental/new VoIP rate search engine. > > --- On Sun, 1/4/09, Alex Balashov <abalas...@evaristesys.com> wrote: > >> Many of them have claimed they lose a ton of money from >> accounting problems caused by the unreliability of signaling >> (as though SIP doesn't have reliable retransmission of transactional >> messages or something) but they've never shown me any numbers to >> substantiate that. > > OK, here's some statistics for the month of December for > the carrier in question: > > Our record shows: > 100,504 calls > 130,740:27 minutes total > > Their record shows: > 100,161 calls (probably just time difference here > 179,811.28 minutes total > > Their record shows total rate charged $229 higher than what > our billing system determined we SHOULD have been charged. > In other words- $229 extra have been charged due to signaling > problems - and this is just one month. > > I used to ask them for refunds for these but to be honest it's > such a PITA that I just gave up and started routing most of > our traffic to other carriers. > > Bad billing is bad for business no matter how great your > call quality is. :) > > -- Nitzan > http://www.comparevoipproviderrates.com/ > > _______________________________________________ > --Bandwidth and Colocation Provided by http://www.api-digital.com-- > > asterisk-biz mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-biz _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
