Free PC to PC SIP Service Providers
The following SIP service providers allow you to make free, worldwide calls using Express Talk and our other VoIP software.
Most of these companies can offer free PC-to-PC calls because they make their money from providing PC-to-Phone connection services.

PC to Landline SIP Service Providers
These providers offer a gateway service allowing you to make and receive calls from traditional telephone numbers. There are fees for this service but they tend to be cheaper than those from the phone company.
When choosing a provider, it is usually better to pick one who services your area, but if you are calling a particular country a significant amount, choosing a provider from that country can potentially further reduce your costs.

Call Centric (Canada, USA, Europe, International)
** Video Phone Capable **
Call Centric offer a good service. They are based in the USA and are a recommended option.
BBPGlobal (Australia, Canada and International)
BBPGlobal is one of our favorite IP-to-IP services because they have servers in so many countries and their technical tests pass on all points. They are also useful because the same account can be used for free IP-to-IP service and lets you signup for a real phone number later (see right column).
IPTel (USA)
IPTel is a non-commercial service, it lets you ring people subscribed to other providers (just type in their full SIP address). It is one of our favorite services for computer-to-computer calls.
VoIPtalk (UK)
VoIPtalk is a large UK & European provider that you can use for free to call VoIPtalk or other PC SIP users. Maybe if you are in the UK you could try this service.
DrayTEL (UK)
DrayTel is UK provider whose "no-frills" free service lets you call DrayTel and other users.
SipGate (UK)
Sipgate is a UK provider whose free service lets you ring other Sipgate customers only. This provider does not support on-hold and transfer mechanisms when making phone calls, only use it if you want a basic service.

InPhonex (USA, UK)
InPhonex is a good provider who have gateways all around the world so you mostly only get charged local rates for that country. All audio is relayed through their servers, so some communication delays may result.
BBPGlobal (Australia, Canada, NZ)
BBPGlobal is our recommended Australian provider because it was the only company who passed all our technical compliance tests with full marks. They are also good because you can sign up for a free IP-to-IP account first so that you can test your setup, and you can upgrade to a real phone number later. On pricing their real phone number rates (and call rates) are cheaper than the other providers we reviewed for Australia, Canada and New Zealand. Note: To see land line pricing and call rates you need to fill out the form for a free account then use your account manager.
VoIPtalk (UK)
A popular UK provider.
DrayTEL (UK)
A good UK provider offering a basic service. If you just want something that works without any of the extra features and add-ons, DrayTel is a good option.
Sipgate (UK)
Sipgate offer a basic service that lets you ring any landline number you like, but it won't let you use on-hold or transferring functionality.

Please Note: Many providers will give you an option to download their own branded version of Express Talk or other softphone. We recommend you use the standard Express Talk version from the Express Talk Softphone Download Page to avoid being locked into a single provider, so you will be free to assign different providers to different lines, or change services later. If you have already downloaded Express Talk softphone there is no need to download the softphone again after signup.
