Hi, We have a system configured with D300JCTE1120E boards and we are having problems when a call is received from GSM or NGN networks. The communication is done but the call has serious problems. the audio is so loud and the call is going and caming all the time. We would like to know if there are any parameter or configuration we can change and modify to improve the gain in the calls. Note that the calls from other networks are working properly. Is anyone can help me with this task, as is happening in a production environmnet and it is giving us lots of problems. thanks in advanced for your help. best regards
