If you are looking for how to activate call forwarding in MagicJack device then read the article below.   

MagicJack doesn't offer conditional telephony, however, there are 2 ways to urge call forwarding MagicJack. For this you need to use your YouMail dropbox: 

1. Log in to your account by going to my.magicjack.com
2. Here go to "Account e-mail"
3. Enter your MailPhoneNumber @my.youmail.com as an extra e-mail address, and choose voicemail.
EX: If your YouMail account is 9500245678, you'll enter 9500245678@my.youmail.com

Note: take a look at your affiliation to YouMail by vocation your magicJack and feat a voicemail. Sometimes, magicJack doesn't create the amendment, although it displays properly on your screen. In such a case, you would like to contact their client support. They sometimes reset your system and you get your YouMail in operating within minutes. 

The other technique is to own the MagicJack either forward to your cellular phone or forward on to YouMail (depending on whether or not you would like magicJack calls to travel straight to voicemail). To do so:
1. Add your magicJack variety as a YouMail phone here
2. Log in your magicJack account by going to my.magicjack.com
3. Select "Call Forwarding"
4. Enter your cell phone number and enable call forwarding.

In case, you come across an error in your MagicJack device or you need any support with the issues you are facing so you can directly contact 24/7 available tech support helpline. For this, you need to call MagicJack Customer Service.
