my SER and SERWEB have a good run, but my SEMS have not speak.

when I use sems -E , I have some error :

(4939) WARNING: reloadModuleConfig (SemsConfiguration.cpp:66): no configuration found for module isdngw, maybe you want to specify config.isdngw in config file.(4939) ERROR: send (AmRtpPacket.cpp:119): while sending RTP packet: Invalid argument (4939) ERROR: send (AmRtpStream.cpp:179): while sending RTP packet.(4939) ERROR: send (AmRtpPacket.cpp:119): while sending RTP packet: Invalid argument (4939) ERROR: send (AmRtpStream.cpp:179): while sending RTP packet.

and next is my conf file.
