Least Cost Routing of VOIP Calls

[shailendra.gupta]

Dear Friends

Please suggest methods/resources to implement least cost routing of VOIP calls, such that the VOIP Gatekeeper interact with Billing Server, which has information of all rate plans,and decide the destination VOIP GW/E1 Ports to hand over the call to a specific Basic Service/Access Provider which provides the better rate at that moment.

Thanks & Regards

Shailendra

Usually it is cheaper to aggregate all your PSTN minutes to 1 carrier.

By the time you try and figure out all the least paths you can find a carrier for 2-6cents/minute. If you do it yourself you have more hardware spread out, higher costs of ownership, etc.

You have intra-lata and other issues. Their are companies that publish cd-roms of tarrif tables, etc. Your subscription cost more than the benefit.

From a international standpoint you have to worry about completion rates, etc. So Sprint may have a better rate, yet none of the calls will complete other than AT&T.

We have a product that in final beta at the moment. It run on a SUN Solaris platform, does SS7, H323 gateway, billing and LCR.

Its unfortunally geared for large carriers and not individual or Enterprise users.

If you have such a need e-mail me.
