Hello! I have following problem: My current session is connected to a thirdParty Application by using an own FreeSwitch application "DoingReadAndWriteFrames". The communication between FreeSwitch Session and thirdParty Application is done by reading and writing frames in a while loop. At start of FreeSwitch Session the communication works without delay. After three or more hours i get a communication delay of one or more seconds. If i hang up and make a new call (a new freeswitch session), than the delay disappears, but after several hours the delay comes up again. It is possible, that i get an old frame (one second ago) with switch_core_session_read_frame ? Is there a solution (for example an freeswitch core api call) to avoid the delay ?
