I’ve been dorking around with Asterisk 1.8 RC4 and Exchange 2010 in an attempt to get unsolicited MWI from Exchange showing up on two test phones.
When I leave a voicemail message on one mailbox, Exchange sends MWI to Asterisk, and while it does work, it’s lighting the MWI on both my test phones and not just the phone assigned to the mailbox I left a message on.
Here are the sip.conf entries for the Exchange server as well as my two test phones:
[exchange] type=peer host=10.1.10.21 insecure=invite transport=tcp port=5065 context=from-exchange unsolicited_mailbox=1500  callerid = Lester Tester <1001> host=dynamic secret=monopoly type=friend context=sip-outbound mailbox=1500@SIP_Remote  callerid=Sammy Sample <1002> host=dynamic secret=monopoly type=friend context=sip-outbound mailbox=1500@SIP_Remote
Is there something I’m missing in the configs? Any help would be much appreciated. Thanks!
