Public IM cannot send messages to Lync RRS feed

  • Question

  • I have had Public IM working fine on OCS and now Lync for some years, however recently MSN users are unable to send messages to our Lync users. The internal Lync user gets notification of a new conversation with the the MSN user but the conversation window is blank and the MSN user gets an error. Lync users appear to be able to send outbound messages to MSN users just fine.

    I'm seeing messages in Snooper along the lines of 'SIP/2.0 481 Call Leg/Transaction Does Not Exist'

    I have a suspicion that this may be related to HLB on the Edger server external interface side. I will experiment a bit and see.

    Anyone have any advice?

  • This is resolved now, I had ommited to add the pool DNS load balancing record of one of the front end servers.
