Lync Federation For Additional Supported Sip Domains

As you know for federation there is srv record     and you must create this record if you want that other organization can find your edge server (Access Edge service(FQDN)). In my experience thare was a moment when i need to make federation for additional supported sip domain (not Default sip domain), in this moment we have situation when edge fqdn domain and sip domain is different. for example we have default domain, edge FQDN and in this topology we have additional supported SIP domain



so if you make srv record  it will work and other organizations will federate to you ( without Access Edge Service FQDN



picture for your partner organization that need federation to you


but if you make record your partner cannot federate automatically( ), your federated partner must manually add Access edge Service FQDN


Thanks :)
