In our application the users SIP phones are connected continuously.
An user can select a seconds incoming or outgoing SIP connection. The select second call is connected to the first call with gc_Listen() and disconnected with gc_UnListen().
This work fine for a few hours, but the longer the SIP phones are connected, the bigger becomes the delay in de SIP audio stream. When the SIP phone of the user is reconnected, then it works fine again for a few hours.
Can somebody explain me what is causing de delay in de SIP voice stream of the long connected SIP connection?
Is it possible to prevent/reset the delay without reconnecting the first connection?
