I have programmed the SPA9000 with SIP from Callcentric with (1) SPA525G phone and (1) SPA962 phone. I am using the Callcentric voice mailbox. I have my SPA525G phone programmed so that I can push the vmm button and it calls my mailbox where I can retrieve my messages. However, I can not figure out how to program either the SPA9000 or the SPA525G phone so that the MWI comes on when I receive a message in my Callcentric mailbox.
