Hi all,
does anyone know if the SX10 need a sip registar (CUCM or VCS) to do any call?
for example I my customer need only 2 SX10, does he need a also a cucm or vcs for do a call between them?
otherwise, can I do a call between them only with ip address without any sip registar? like 2 sx20 ..
thanks in advance,
Carlo
