Yes, you can. If you are not with your VoIP device, you can still take advantage of DrayTEL's low calling rates to call worldwide. This can be from a mobile phone or landline using your inclusive/free minutes where available (alternatively, you will pay for the call to the DrayTEL server, but that is still normally cheaper than international direct dial). To do this, dial 020 7099 8207 and enter your DrayTEL username and password. You can then make calls using your DrayTEL credit at your DrayTEL current tariff.
