Hello Prashant,


We are currently in the middle of a VOIP RFP.  I personally support the routing and switching for UMD, but understand that we are currently looking seriously at Kerberos as well so your suggestion is very good.

Subject: [] Kerberos based authentication for SIP


Hello All,


Recently I spoke to some of our customers and they said that SIP RFC 3261 not supporting Kerberos based authentication is a huge problem in the University environment since there is no mechanism in HTTP digest to get the the un-hashed password (token) back.


Is there a huge interest for Kerberos Authentication in SIP environment? If yes, I could work on a draft which proposes Kerboros based authentication scheme in SIP.
