How do you make calls? Via a PSTN gateway or provider?

How do you make calls with 3CX Phone System? Do you still rely on a PSTN Gateway or do you use a VoIP Provider? If you use a VoIP provider do you still use a gateway for backup purposes? If a gateway do you use an analog, ISDN or E1/T1 gateway? We’d love to hear your feedback!

  1. Great way of using your landline on your mobile phone.
    We can ring the UK from France on our mobile phone using our Manchester telephone (number) line at a cost of less than 1/2p per minute.
    Customers can now call us in France at the cost of a local call. Now I have the system on my mbile (Google) phone, I can answer calls when away from home (as long as I am connected to a WiFi source) by either system. (mobile/voip)

    Poll answers didn’t really fit what we do. We are in the US, however have customers all around the globe.

    We have three VOIP providers, with local numbers in Australia, Canada and the UK. Calls to numbers in these areas are routed to the VOIP that handles calls in that area.

    Calls that are long distance but in the US are routed to a different VOIP provider.

    Local/911 calls are routed over a Patton T1 gateway on a PRI.

    Inbound calls including our primary 800# are via the gateway/PRI. The local numbers are published on our website and customers in areas we have local numbers call them directly.

  4. We pretty much mix and match Trunks to gateways depending on customer size and needs. A quality ITSP would be my first choice for in and out calls, however customers with high volumes of calls to mobiles would benefit from a GSM to VoIP Gateway such as the dual SIM which works a treat on 3CX.

    Another option is to use Patton analogue gateways – reliable but a bit pricey in the UK as they’re pegged to the $.

  5. In South Africa the VoIP market is still in its infancy stage and we are still very much restricted by legislation. To have direct VoIP links is still too expensive and using ADSL lines we find it is unstable due to fact that “control” is lost once it enters the “cloud”. Basic Rate ISDN, Analogue and PRI is still the preferred method of connecting. There is however light at the end of the tunnel for VoIP in South Africa.

    We rely on a PSTN gateway for exisng inbound numbers and local calls and the voip providers in two countries fro new inbound and outbound calls including mobiles.
