Re: [Serusers] multi register

So then to take care of SIP phones that can only register with just ONE server SER must work as a proxy and catch the ip information from REGISTER requests inorder to pass a REFER or INVITE from a call generator engine. Clearly the major G/W's have a solution for allowing NAT'd sip phones to call out. The challenge is for a solution provider to stand in the middle and add features such as click to call, or simply allow sip to sip calls as SERVERS such as ICONNECT which have no interest in offering any service other than the PSTN G/W function. Somehow SER can stand its ground as a middleman and offer the SIP clients additional features such as sip to sip dialing and web dialing , or even a CHOICE of commerical SERVERS. I guess some companies have figured this out and are offering a solution ? As it would likely take a major s/w effort to create a middleman solution based on SER ? thx Jan Janak <jan(a)iptel.org> wrote: SER can forward a REGISTER message, even fork it, but it cannot respond to digest challenge. That means if one of the servers sends a 401 Unauthorized then SER cannot generate a new REGISTER message with digest credentials. Jan.
