I'm provisioning some SPA502g phones via an XML document template from the Cisco Support site and i'm running into a small problem. I want to make the username for the sip extension the same as the MAC address of the phone. But when I put in $MAC which should be read as a variable it uses the literal "$MAC" and actually tries to authenticate to the sip provider as such.
How within the XML can I set variables up to be inturptered and not used literally?
