XMPP gateway with Lync2010 RRS feed

  • Question

  • Start-Line: SIP/2.0 403 Forbidden Cannot route this type of SIP request to or from federated partners";source="sip.domain.co.uk"

    Very simple deployment. One Edge server already federated with a number of allowed domains and public providers such as LyncOnline. One Std edition multi-role front end. One XMPP gateway with the binaries installed and configured. I used these two guides to configure and followed to the letter:



    Despite following both guides accurately i get the error above which clearly means a mis-configuration somewhere but the Lync logger is somewhat vague as to what the error is. Can anyone give me some precise pointers as to where the error is when my Edge configuration is correct. My firewall has the correct port 5269 inbound to the XMPP gateway and validation checks from the OCS console pass correctly. The certificate on the XMPP gateway is also installed into the certificate store on each server (FE and Edge). Although this certificate is self signed having only one domain name which is the internal domain name of the server: xmpp.testdomain.local. Whereas the external domain configured is sip.domain.co.uk with a domain name of domain.co.uk under the SIP configuration in the XMPP Gateway. SRV records in public DNS are resolvable as well as internal DNS with a split brain DNS. The Edge and XMPP gateway both reside in the secure LAN in workgroup(s) behind the firewall as this is only a lab setup. My guess is this is either certificate or possibly DNS related. But iv gone over both with a fine tooth coombe and can see no obvious errors. Thanks in advance.

  • Try the NextPlane Federation Cloud Service to federate Lync with XMPP domains - nothing to install and no on-premise components.
