Does the gateway support early media with 183 session progress instead of 180 ringing? 100rel support? It is critical for calls to switched-off mobile phones etc

  In looking at the spec sheet, there is no mention of support for RFC3262 which is 100rel. I also saw nothing in the manual nor in the demo to indicate the function.  

  However, in looking at the spec sheet for the S PBX, there is also no mention of RFC3262; yet there is a setting within the web interface of the unit that allows 100rel to be enabled. 

  While I am of the opinion that 100rel is not available, you may need to contact support directly to get the definitive answer.
