IVR Service capable of concurrent calls

    Hi: I would like to establish an IVR service capable of dealing with simultaneous users. This would initially be low volume (maybe 5 concurrent calls though I would like to allow for expansion).

    I would prefer an Irish +353 number though this is not imperative and I would consider others +1, +44, etc. The important thing would be for the number to be accessible from standard (POTS) phones.

    I have a number of questions in relation to this:

    Can I use Asterisk as a gateway to a standard PSTN line? What I mean is can user Asterisk to split the incoming calls to a standard 01 telephone line and route those calls to different IP addresses on the LAN?

    Assuming I can't do this can I use a broadband service provider like blueface? Do I then use the SIP protocol to route incoming calls?

    I have seen the service operated by IP http://www.ipcomms.net/. Does anybody have any comments on the suitability or otherwise of this kind of service? Are there any Irish/European-based alternatives?

    Am I over-complicating things? (wouldn't be the first time)... I don't have any experience in this arena but I am techically competent. What is the cheapest/simplest way of accomplishing this? I would appreciate some details on what hardware/software that would be required.

    regards,

    SFK.

    Absolutely, you can have normal PSTN lines presented to Asterisk on analogue, BRI (Basic Rate ISDN) or PRI (Primary Rate ISDN) lines. You simply put the relevant cards inside your Asterisk server depending on the type of lines you want to use and then connect your incoming lines to them.

    Assuming I can't do this can I use a broadband service provider like blueface? Do I then use the SIP protocol to route incoming calls?

    And/or you can also use SIP or IAX for incoming calls as well as normal landlines. In this case the calls would terminate initially with your VoIP provider(s) and they would forward them to you via SIP or IAX.

    To clarify: can I take one standard PSTN analogue line and split that into a number of channels using Asterisk. Presumably by "card" in terms of PSTN you mean a standard PCI voice modem? Regarding the other options (ISDN), can you recommend any particular cards?

    If I did pursue this option (voip) would users be able to call the service using standard (POTS) phones? (via an 076 number?)

    You can only have 1 call per incoming analogue line (you can have 30 on a PRI). By "card" I mean , for example, those supplied by Digium. Have a look at their hardware range on their website. Sangoma also do some of the higher-end cards.

    Yes, if you wanted a normal geographic (e.g. 01-, 021-) number then this would need to be supplied by or ported to a VoIP provider so that they can send the calls to you using VoIP. 076 numbers would work in the same way.
