Applies to version(s): v2.9 and above

In this scenario, all messages from TDM network are relayed to the IP network via Sigtran: M2UA

Note: This implementation, although based on standards, is proprietary. Normally, one end is the SG and the other is the MGC. So in this use case, one of the TMGs simulates the MGC. All of this is transparent to the TDM devices interconnected over IP.

  • Toolpack:Creating_M2UA_Links_C. You need to modify the default behavior or some reason causes:
    • Profiles -> Edit Reason Cause Mapping
      • 300 Multiple Choices-> Route retry action -> Stop Call

Do this for all Reason Cause that will be used

  • Create normal routes to the redirect server: Toolpack:Toolpack:Creating_M2UA_Links_C:
    • Routes -> Create New Static Route
      • Name -> To_SIP_Redirect_Server
      • NAP -> any
      • Remapped_NAP -> NAP_SIP_REDIRECT
