Re: Exchange 2013 UM and CUCM 8.6

Per our setup:

For the SIP Security Profile, your CM listens for your Exchange servers on 5060 and you should be able to use the same profile for both trunks.

For the SIP trunks, the CAS service listens on 5060 and the mailbox service listens on 5062.

Re: Exchange 2013 UM and CUCM 8.6

In CAS SIP Trunk settings on one trunk I have this


I am trying to create Mailbox server trunk with following settings


and I am getting error

SIP Security profile

when I am trying to save the trunk

in the example CAS and Mailbox server rolls are combined (same as what we have)

but its not possible in CCM to create 2 trunks to the same server (with different destinatino ports) with same SIP security profile , because CCM listens on port specified in SIP Security profile

Re: Exchange 2013 UM and CUCM 8.6

I encountered the same issue as this post on my own CUCM 8.6 and Exchange Server 2013 CU2 environment.

Then, according to Daniel's work-around, I could successfully solve it, while I don't really know

the root cause of it especially whether it is design or not...

At any rate, Thanks!

Exchange 2013 UM and CUCM 8.6

I am having the same error "Both have the same Incoming Port "5060" and hope someone can help.

Re: Exchange 2013 UM and CUCM 8.6

We are runing CM 9.1.2 & Exch2013

There are two trunks. The 1st trunk points to the CAS server using it's IP address and destination port of 5060.

The CAS server redirects to the UM server via a CONTACT header it sends back to CM, the contact header contains the UM servers FQDN, not it's ip address.

So now CM needs a SIP route to the UM server. (This is the FQDN of your UM server)

The 2nd trunk ponts to the UM server using it's FQDN, and destination port 5062.

Below is needed on the SIP profile to assure that SIP routing is used.

We have a single SIP Security Profile that both trunks use, and it listens on 5060.

Thank you very much

Exchange 2013 UM and CUCM 8.6

I started with Exchange UM and CUCM back in Exchange 2007, then migrated to Exchange 2010 with no real trouble. When trying to get to Exchange 2013, though, it all hit the fan. Even once I updated my existing SIP Trunk with the 2013 mailbox server and port 5062 there was up to a ten-second delay from the time I pressed the messages button until Exchange 2013 answered.

After following your steps, Daniel, the delay is gone. Thank you very much for your terrific step-by-step directions! I truly appreciate it!

I have the trunks and the SIP

I have the trunks and the SIP route pattarns created just as Daniel post. You press the messages button on the phone it works great.

My problem:

If you call the pilot number from a phone that has no voicemail associated, the Exchange will prompt for extension (that is good). Once you enter a valid extension, Exchange will ask you again to enter your extension, this time when you enter the extension it works. What I think is happening is the request first goes to CAS Exchange server , it sends a refer back to CUCM to go to server 3 that has the user mailbox but CUCM sends a request to server 2 instead ignoring the refer and then goes server 3. So we get double prompts to enter extension.

Has anyone exprerence this? Is there a fix?

Thanks,

Solomon

I am hitting the same issue, did you manage to fix it by upgrading? I have an upgrade scheduled for Q2 this year though the exchange team have just upgraded to 2013 and we have hit this bug!

I appreciate any help, I have implemented using Daniels notes above including using SIP routing for the mailbox servers. I am running CUCM 8.6.2.23900-10

We hear you.  :)  Working on

If anyone from Microsoft is reading this please update your documentation as it's not "just the same as 2010".

We hear you.  :)  Working on it... 

The name field in ip gateway

for info:

The name field in ip gateway definition in MS Exchange 2016 must contains the ip address of the CUCM. Otherwise, an error - 

ms-diagnostics-public: 15602;source="EXCH-01.test.com";reason="The Unified Messaging server is not authorized to accept calls from this SIP peer."

p.s. Take tcpdump from Exchange server with "netsh trace" command and analyze it with MS Network Monitor.

p.s. My environment - Exchange 2016 and CUCM 11
