Supernode protocoldialing
From MIXvoip wiki
Through MIXvoip you can do do direct SIP or IAX calls. Unfortunately entering a SIP URI or IAX URI into a softphone cab break the protocol because of special characters like '@'. Therefore we created a protocol friendly syntax. Just place a call to a remote SIP or IAX URI by using one of the possible syntaxes below. You can use this either on your PBX or any softphone.
SIP URI calls
Format: SIP##SERVER##PORT##NUMBER
SERVER: IP address or fully qualified domain name of the remote server
PORT: The port number. If nothing is specified we will use 5060 as default port
NUMBER: The destination number you want to call on the remote server. optional
SKYPE buddy dialing
Format: SKYPE##SKYPE-BUDDY-NAME
SKYPE-BUDDY-NAME: just the skype buddy you want to call
