Recently I took a note on the site of the wonderful service
gtalk2voip.com to see what new baubles appeared and saw interesting news for January 29th about the service
www.groovytel.comIn short - a personalized US phone number with the possibility of redirection to Google Talk, MSN Messenger, Yahoo Messenger, Free World Dialup, Gizmo5. When registering, you can choose a number from 3 offered, they gave me the form + 15672587XXX. It really works checked only on gtalk. When making a call, gtalk receives a call from the subscriber with a phone number (if determined).
Similar services: gobaza, jetnumbers.

After
surfing the Internet, I found another site,
www.ipkall.com, which has great advantages over groovytel (for me personally) in its ability to use hardware solutions (supports SIP and IAX). I set up a redirect to the sipnet.ru account which is running on AudioCodes MP-202. Now you do not need a computer to receive calls and you can use a regular phone device =)
Also free tel. number in Germany (Munich) of the form +49 (89) 721010 XXXXX
gives sip operator
www.bluesip.net does not support redirecting to another sip account.
