I'm evaluating XMPP servers. It looks like Lync 2013 supports XMPP. Here are the requirements:
Server able to send and receive messages from/to any mobile device. We need to use our custom app (B2C app). (can't use Lync client app)
1. I think Lync has CAL based licensing which will not work for us since nature of apps. We cannot CAL each user.
2. I think Lync API's not available for Android/iOS. We could use standard XMPP libraries provided it inter-operates well with Lync.
3. If Lynch is not the right product, is there any other Microsoft product offers this solution?
Anyone has experience with these scenarios? Thank you.
