Determine which SIP Domains You Federated With RRS feed

  • Question

  • Hi There,

    We have SfB Server 2015 with Open Enhanced Federation. We are considering changing to Allowed Partner Domain/Enhanced federation but before we do that we need to know which SIP domains we are currently communicating with. Is there an easy way to do this, possibly a SQL query to run on the LcsCDR database?

    Cheers

  • Hi

    Based in your description, I understand that you want to check which organization you federated with, based on my research, for Lync server side, there is no method to find this out.

    With Discovered Partner Domain federation, Skype or Lync accepts any SIP domain name and uses DNS records to locate the partner organization's Access Edge server. What makes this possible is the interaction with the public DNS records that are created by the partner organization. The partner organization needs to create two DNS records:
    1.A DNS SRV record specifying the domain. It should follow the format _sipfederationtls._tcp.domain.com. The port value for the SRV record should be TCP 5061.
    2.A DNS A record containing the Fully Qualified Domain Name (FQDN) of the Access Edge server. It should follow the format sip.domain.com.

    Please refer to the following about discover Partner domain

  • Yeah, I know how the different types of Federation work.

    What I was wondering is if there is a way to determine which SIP domains my users are communicating with. The LCsCDR database records all communication so I was wondering if there was a query i could run that would return the all those external SIP domains?

  • Hi broonster,

    Thanks for your response.

    Based on my research, there is no method to check this in server side.

    It seems that the backend database not have this information neither.

    For your scene, you want to set to allowed partner domain, you can just add your partner organizations' SIP domains to the list of federated domains in the control panel.

    Michael,

    That's a very interesting post indeed, thank you. However it looks as though it will only return results for "discovered" partners. We have open federation but some of our partners use "enhanced" or "direct" federation and I don't think the command in that post will return records for those will it?

    Cheers

    Yes, it seems that the command won't return the records.
