Skype Connect Asterisk Dialplan

Does anyone know how to setup the outgoing (from asterisk to skype) dialplan for Asterisk and Skype Connect?
Currently, I have:

exten => 4321,1,Answer()
exten => 4321,n,Dial(SIP/skype/sip.skype.com/myskypeusername)
exten => 4321,n,Hangup()

myskypeusername is replaced ith my actual personal username which is active (logged in) while I make the call.
however, I am having issues

Any help would be appreciated

There are two many /s in our resource address.

Also, you would normally use a sip.conf entry rather than providing the IP address directly.
