  • Here is how i have resolved this issue,

    I have a forwarder in our child domain to the root domain for the root domain DNS zone, I then created the _ntp and _sipinternaltls DNS entries in the root domain DNS zone and I re-configured my user object in OCS to log in using the UPN of my user object.

    Problem solved.

    Thanks to all for your input.

  • Have you also externally published the DNS A record for the Access Edge FQDN (e.g. sip.domain.com) which is referenced by the SRV records?

     

    Actually, where is the phone located, inside your network or outside?  I'm not sure if 'No Federation server' means no Edge server or simply no federation configured.

  • Hi,

    Thank you for your reply, I have no Edge server, was wondering if this was a pre-requisite?

    The phones will on our internal network, however, we are a very distributed organisation with numerous subnets.

    Regards,

  • Are you normal clients configured for Automatic or Manual lookup?  It appears as though either the phones can't locate the OCS servername or lookups work but then network connectivity to the Front-End server fails.

  • How do I check this setting on the OCS server?

    I can resolve the servername IP address via pinging the servername.

    Pinging servername.childdomain.rootdomain.x [x.x.x.x] with 32 bytes of data:

    Reply from x.x.x.x: bytes=32 time<1ms TTL=128

    Ping statistics for
