[cisco-voip] PSTN E.164 call routing

[Ryan O'Connell]

That is exactly what I'm trying to achieve is less route plan entries, and a much cleaner design overall. Back to the Calgary example, area code 403 is shared between Local calls and Long distance calls, and that is just one of 2 area codes for this region. If I want to designate which NNX is local vs LD based on the gateway it is leaving the network from then I would need to write patterns for each, not only that I would have to keep them current ass NNX's are added into the NANP. No Thanks. Cleaner would be to ship a fully qualified number out and let the telco figure it out. So back to my question do you know if this is possible to achieve? I'm pretty sure this can be done using SIP trunks to the service provider but not so sure on the traditional side as in PRI circuits.

I am not sure I am following what you are saying where I could achieve this by creatively selecting which GW certain area codes exit the network from, essentially making all calls long distance? Is this what you are suggesting?

Thoughts

Hi Ryan,

Are you able to dial the full E164 number by using the international access code? I would have thought this would work?

This would usually come down to your dialplan design.. i.e. route a call out a certain circuit, and make sure that you are sending the digits required on that circuit so the call can be completed.. this can be different for providers, or could be different if you throw the call out a remote gateway or something for example...

What are you really trying to achieve? Are you just trying to use less route plan entries :)

Cheers,

Tim

Does anyone know if service providers have any present day capabilities or future plans to pass full e.164 numbers. For example we want to pass full numbers to the PSTN whether they are local or long distance and let the carrier figure it out very similar to how it works on the Mobil networks. So today if we are in Calgary and we want to dial another Calgary number we must dial 4031234567, if we dial the same number with a leading 1 then the call gets rejected. Is there any means to make it like it is on the mobile network where if the same number is dialed with the 1 so 14031234567, while in Calgary, and the call gets passed? I know with the introduction to SIP trunking services they would have to take both the 10 digit local number and the 11 digit equivalent and route it accordingly because the point of entry into the PSTN cloud may not necessarily be local. If this is the case I wonder if it's possible with TDM circuits as well?



Thoughts?
