Hello PeterIf user doesn't provide any Authentication information in INVITE message what response should come for this? Like In Register, we are getting 401/407 for Authentication Credentials.Santosh

The user would still need to get authenticated when it sends out theINVITE. If the authentication for the INVITE passes (it uses the samecredentials as the authentication pwd for registrations), you wouldaccept the request for the outbound call and bill based on the billingrecord created by that call.Peter-----Original Message-----From: discussion-bounces at sipforum.org[mailto:discussion-bounces at sipforum.org] On Behalf Of Raghu NarasimhanSent: Tuesday, May 01, 2007 8:40 AMTo: reliagility at gmail.comCc: discussion at sipforum.orgSubject: Re: [SIPForum-discussion] Issue in Initiation/Termination ofcallwith De-Registered Userdoesn't everything go haywire then ? un-regged user makes call.. whogets charged ?On 5/1/07, Michael Cohen <reliagility at gmail.com> wrote:> Hi all.
