Hi Amit,

 

USEE A---->SBC1----->SBC2------>TDM g/w1-------->mobile MSC--------->USER B

|                                                             |            |                                                              |

---------------------SIP ----------------              -----------------PLMN-------------------

 

You should verify if G723 is the only codec supported by USEEA and if the TDM GW doesn't support this type of codec. You should also check the sample size used : 30ms for example.

 

« Incompatible media type » is the response if the TDM g/w doesn't support G723codec.
