Calling Other VoIP Networks

iPhox can call over one hundred VoIP networks around the world for free. However, as each network uses different numbering plans, it is not always as simple as dialing a normal telephone number.

These same networks can call your iPhox account by dialing the SIP account number, which looks like 1-747-XXX-XXXX. Some networks will need to dial this as an international number. While all calls to your account are free to you, your friend should check with their individual provider to verify the call to iPhox’s parent network, SIPphone.

Below you will find a list of VoIP networks and other peered networks with instructions on how to dial their members:

X = the given account number of the person you are calling.
