Can I change the host part of the SIP message header to be the mediation server IP instead of FQDN RRS feed

  • Question

  • Hi all, I am trying to setup a SIP trunk and my provider ask me to put a Mediation Server IP address that is faced to them instead of FQDN of the Mediation Server.

    I am using OCS 2007 R2 ent.

    So basically I want my message header for outgoing calls to be +1555xxxx@<IP address> instead of +1555xxxx@<FQDN>

    Is this can be done, and how?

  • Im faced with the same issue, however the provider I am trying to use is not certified by MS although they do support SIP over TCP. I'd be interested to hear if you have found a solution yet?

    Many thanks

  • Hi Adam,

    My provider find a way to "recognize" me by FQDN of the Mediation Server so I stopped looking for а solution.

  • Hello Adam,

    I know that this can be done using SBC's - for example the Acme Net-Net SBC.
    Please see slide 9 of this presentation.


    Now, I do understand that you would not get a SBC and place it at a customer site, but your operator should be able to fix this in case they are
    terminating your SIP Trunk in an SBC device.

  • Was anyone ever able to figure out if this can be done?

    I am facing the same request from my provider.
