Hi All, Another query.
Lets say I have deployed a SIP proxy - "PROXY-A" to which a very large number of users are registered. I need to bring down PROXY-A for maintenance and replace it with PROXY-B but donot want the users to register again. Is there some way by which PROXY-B can pull the info out of PROXY-A so that the customers donot see this transition. Is it possible for a SIP Proxy to fwd all the learnt registration information to a backend central registrar. If any call needs to be routed (eg: an invite message being received) the proxy can lookup the central registrar and route the call . I want to know if this is a valid config and do any SIP proxies support this as of now. thanks, sandeep On 10/20/05, sandeep kamath <[EMAIL PROTECTED]> wrote: > > Hi Dale, > Thanks for the info.

There is no mechanism in SIP for this.
