Lync 2010 - Direct SIP Trunk - Call Forward Fails RRS feed

  • Question

  • Doing a Call forward fails because the SIP provider doesn't accept, that the Contact-Field of the SIP-Invite is filled with another domain name compared to the FROM-Field.

    FROM: <sip:+123456@domain.tld;user=phone>CONTACT: <sip:hostname.domain.local:5060;...>

    The provider answers with Error 400 bad r-uri

    Any suggestions?

  • Hi,

    Is the provider Microsoft Certified SIP Provider? if not, some of the features might not work. you will need to use a recommended Gateway like NET or Audiocodes to get the full feature transparency over the SIP Trunk.
