Almost everything else on the planet except Skype uses SIP and they all interwork. You can inspect your SIP code and be sure it contains no suprises while you can't with Skype - see http://www.theregister.co.uk/2008/07/25/skype_backdoor_rumours/ and the stuff about China and Skype. With open source you could verify the situation, with Skype you can't. Skype is essentially the MS Windows of the VoIP world: proprietary and closed. It talks to nothing but itself, and even encrypts its own binaries to prevent people reverse engineering it. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
