Tengo configurada una centralita Voip Elastix y un equipo Gateway GSM Portech MV374 (con 4 lineas de moviles) con los que salen las llamadas. El problema es que las llamadas no se escuchan bien a veces. La voz se escucha entrecortada a veces. En otros momentos la llamada se escucha perfectamente. La troncal esta configurada, las llamadas salen pero , A VECES, no se escuchan bien. Hay que colgar y volver a llamar y al hacerlo , se escucha bien y a veces no. Es decir, el problema es que se establecen las llamadas pero , a veces, no se escucha bien. Las llamadas se realizan desde republica dominicana conectandonos a traves de softphones zoiper a la centralita Voip Elastix en Barcelona (España). El problema tendria que estar en la centralita en España. Llamamos sin proble...
