I have been struggling a few days with connectivity on my external sip domains.
My Setup is as follows: I have 1 standard FE server not publicly accessible.
I have an Edge Server that is publicly exposed but the IP is translated by NAT.
my primary SIP domain is company1.co.za ---> users of this SIP domain can connect internal and external without any issues. all my other SIP domains are giving certificate issues - they are included in the self signed certificate that company1.co.za connects to.
so: company2.co.za company3.co.za ... company15.co.za
none of them can connect.
exporting the certificate with the private key and importing on any of company 2 - 15 then they can connect.
Will buying a DIGICERT certificate be worthwhile or am I missing something.
this Lync development is rapidly expanding so the adding SAN's to the primary cert is going to be an administrative nightmare.
can someone please shed some light on this and give me some pointers...
