OfficeServ 7000 Series Call Server Programming Manual© SAMSUNG Electronics Co., Ltd. 2-371(Continued)No Parameter Description Default06 SILENCE SUP This parameter determines whether silence suppressionis used. This prevents transmission during the silenceperiod of a call, and conserves bandwidth whenenabled.DISABLE07 TO RTP GAIN PCM input gain value of DSP. Direction is from PCM toPacket. The range is 18~38 (-14 dB ~ +6 dB)This set the quality of PCM voice from the VoIP DSP tothe site. Default is 32 (0 dB).32 (0 dB)08 TO PCM GAIN This value selects the voice volume. Direction is fromPacket to PCM. The range is 18~38 (-14 dB ~ +6 dB)32 (0 dB).09 MIN JITTER Decides the minimum time to consider delay for jitteradjustment.The range is 0~150 ms30 ms10 MAX JITTER Decides the maximum time to consider delay for jitteradjustment.The range is 30~200 ms.150 ms11 JITTER AP The Adaptation Period controls the speed at which thejitter buffer can adapt downwards when currentnetwork conditions allow. The larger the value, theslower the jitter buffer adapts down, when jitterdecreases. The value is programmed in milliseconds,with a default of 10000ms (10seconds) and aminimum value of 1000ms (1 second).1 sec12 JITTER AT When the jitter buffer grows past the DeletionThreshold, frames exceeding the deletion threshold aredeleted immediately. Audio quality may be negativelyaffected. This parameter is expressed inmilliseconds, and may be programmed from the valueof the DelayMax up to 500ms.The range is 150 ms~500 ms.250 ms13 T38 FAX USE This option selects the mode of FoIP. If selct Enable, faxprotocol is T.38. In other case, fax protocal is G.711pass through. (This mode should be use G.711 codec)Enable14 T38 REDUND. This option selects retry count of Fax-over-IP if errorsare detected. The range is 0~3 (0 means no retry).315 FAX ECM This option selects retry of Fax-over-IP if errors aredetected.ENABLE16 MAX FAX CNT This is the maximum number of channels that can besimultaneously used for Fax-over-IP. The range is00~04.217 RTCP PERIOD This option selects the interval time for sending RTCP. 5 sec
