Normally echo in a GSM network is presented in calls to/from PSTN.
According to standard GSM Mobile Stations have the capability to reduce this efect but it depends also in which kind of mobile are you using for.
Also in transcoder unit there must be a feature or parameter called acoustic echo canceller when you set delay in miliseconds to indicated the system to cancell echo signal. Recommended value can be from 200 to 400 ms.
