Voip to PSTN

Hi, I am newbie in VOIP. Just want to do something very simple. I am in Melbourne, and we have a branch office in Sydney, with private VPN connection. I want to put a VOIP to PSTN gateway there. So that I can run VOIP client program on my PC, connect to the gateway, and make calls to Sydney through PSTN. By do this, I only pay local calls.

There is no need to connect all the user in Sydney office, as we all use skype.

Not sure what software, hardware can do that.

Thank you.

Why..?! A SIP service using ordinary phones is much better, surely..?

Sipura 3000 will do this -

With Sipura 3000, do I put it in Sydney, connect it to the IP network and PSTN, and use SIP client in Melbourne?

Thanks.

Hi, What I want is very simple. I am in Melbourne city, and I want to put a unit in our Sydney city office. When I need to call someone in Sydney, I can connect from my computer to the unit in Sydney by using our private network, and unit can convert my voice over IP to PSNT. So that I only pay Sydney local calls even though I am calling from Melbourne.

Weili,

You may use a pair of Sipura SPA-3000's . See e.g.

; you may also go through the office's PBX rather than connecting the device to an external line. And the arrangement may be easily made symmetrical: someone calling from Sydney might dial out to Melbourne's PSTN.

If you can't find a local dealer, Sipura products are sold on the web by several internet shops

...). Before choosing one, check not only the price of the unit but also the shipping charges. In my experience, to ship to Hong Kong Telephonyware is the least expensive (~USD 24 for Speedpost/EMS freight, vs ~USD 40 from other shops).

  1. Thank you Valentino for giving me the information. I will have a look at it.

  1. Thank you very much Enzo for pointing the direction. For the Spa-3000 example, I am just wondering if I can use a software SIP client on one sie, and a SPA-3000 on the other side instead of Spa-3000 on both sides.

Thanks.

Yes, but of course a softphone can't do half of the work usually done by the SPA-3000: the connection to the PSTN on its side.
