From Alejandro Vaquero:

Find attached a patch for this bug. The problem was actually in the "Voip Calls" logic, when the first RTP packet was after the last signaling packet (e.g. a call connected and the release not captured), that caused the RTP to not be added to the graph list and therefor to the player.
