Hi guys,

I have 2 questions related to SfB and Exchange UM, I hope you have some time to answer:

1.        Could we have configured more than 1 Exchange Online tenant for VoiceMail on our Onpremise SfB? For example I have tried to add different Tenants/Organizations in this way but it only works for the first one:

Set-CsHostedVoiceMailPolicy Destination exap.um.outlook.com Organization org1.onmicrosoft.com, org2.onmicrosoft.com,...,orgN.onmicrosoft.com

1.        Could we have enable Open federation avoiding the use of sip.domain1.com, sip.domain2.com,...,sip.domainN.com names on the certificate? A colleague sent me a trick but it didn't work for me using cnames:
   • Having a SRV for each sip domain:

_sipfederationtls._tcp.domain1.com to sip.domain1.com

_sipfederationtls._tcp.domain2.com to sip.domain2.com

......................

_sipfederationtls._tcp.domainN.com to sip.domainN.com

• And CNAMEs in this way:

sip.domain1.com to access.maindomain.com

sip.domain2.com to access.maindomain.com

..............

sip.domainN.com to access.maindomain.com

Thank in advance,
