I know the justvoip trick and used it myself up to about 6 weeks ago. The problem now seems to be the quality of forward of justvoip. Whenever I forward a call to either a mobile or fixed line and I call my justvoip sip at
username@sip.justvoip.com the quality is very bad. I mean really very bad.
www.pbxes.com is a virtual telecom pbx. You can setup trunks = incoming and outgoing lines and you can setup extensions = voip phones or regulas pstn phones. In case of pstn phones extensions the call is forwarded using a trunk.
In my case my mobile number is and extension and incoming calls are forwarded.
When using pbxes pro you can have a callback option.
This means that I call a line on a trunk using a phone with caller id. The callback is setup that it recognises the caller id and when making the call you always get a busy signal.
Within 10-20 seconds you receive a callback on your mobile and you will get the dialtone on the pbx and can continue the call.
Using the system this way, a callback to my mobile cost me 10 eurocent per minute (voicetrading) than I can continue the call at the voicetrading or other betamax provider rate.
To most fixed lines the call is free or just 1 cent. This means I can make a call to a fixed line from my mobile for only 11 cents.
The problem I have is that the manx number I have does not recognise dtmf tones anymore. So whenever I receive the callback and want to dial a number, the numbers are not recognised anymore. This means that using the manx number I can't use my callback system anymore.
