Philip, one more idea – in the external clients you can hardcode the FQDN hostname of your Lync or OCS Edge server (in Options, Advanced Sign-In) and attempt to sign-in.

This will tell you if it is DNS issues or some other issue.

Philip, there could be many reasons besides DNS that external users cannot sign-in.

From the information you provided, if you would like external users to sign in automatically using the SIP domain ABC.com, you will need one of these domains resolvable to the access Edge externally in DNS: _sip._tls.ABC.com or sip.ABC.com. Neither of those records are returning a match in DNS based on the results you provided.

I noticed the domain your using in my tool is actually “pgclync.ABC.com”. If that is the external SIP domain you want to support you will need to use that domain instead (i.e. _sip._tls.pgclync.ABC.com or sip.pgclync.ABC.com).

Hope that helps,
Curtis

Please advise, we have 2 SIP domains

ABC.local (ad default)

ABC.com

Please see my results below & advise, what must I do to correct my scenario. All the internal users can sign-in. External users cannot.

Hi Curtis,

There is a user in our company server team give him Audio Video access on OCS, but while using his system user unable to use these features, then i recreate user profile on same system it not works.

So will you suggest me what’s the issue with his profile and need your suggestion on this. Please mail me on ershaktimoudgil@hotmail.com.

Without knowing anything about your situation or environment (e.g. just external contacts or all contacts?, OCS 2007 R2 or Lync on the server side?, was it working at one time and the presence unknown just started?) it is hard to recommend anything.

I can tell you that there were hotfixes released quite some time ago (+1 years) on both the client and server side that have fixed this problem.

Making sure your Communicator 2007 R2 Clients and OCS/Lync Servers are completely up-to-date is a great first step.
