Multiple registrations is a functionality that was built into SIP from
the beginning.  Many, many users of sipXecs have been using it for many
years and we have never seen a fundamental problem with it.  It is not
clear to me who would recommend to you that multiple registration does
not work in SIP.  Is it possible that you are confusing SIP with other
voice-over-IP protocols, some of which do not support multiple
registrations well?

If you have  tried to use multiple registrations and they have not
worked, please tell us about your experiences in detail.  I'm sure the
problem can be corrected.
