  Mediant 500L Gateway & E-SBC 
Parameter  Description 
BRI phone after 2 seconds. As the call duration is less than 
the minimum call duration, the device does not disconnect 
the call on the Tel side. However, it sends a SIP 200 OK 
immediately upon receipt of the BYE to disconnect from the 
IP phone. The call is disconnected from the Tel side only 
when the call duration is greater than or equal to the 
minimum call duration. 
Note: 
  The parameter is applicable to IP-to-Tel and Tel-to-IP 
calls. 
  The parameter is applicable only to ISDN protocols. 
Disconnect on Dial Tone 
configure voip > gateway analog fxo-
setting > disc-on-dial-tone 
[DisconnectOnDialTone] 
Determines whether the device disconnects a call when a dial 
tone is detected from the PBX. 
  [0] Disable = (Default) Call is not released. 
  [1] Enable = Call is released if a dial tone is detected on 
the device's FXO port. 
Note: 
  The parameter is applicable only to FXO interfaces. 
  This option is in addition to the mechanism that 
disconnects a call when either busy or reorder tones are 
detected. 
Send Digit Pattern on Connect 
configure voip > sip-definition 
settings > digit-pttrn-on-conn 
[TelConnectCode] 
Defines a digit pattern to send to the Tel side after a SIP 200 
OK is received from the IP side. The digit pattern is a user-
defined DTMF sequence that is used to indicate an answer 
signal (e.g., for billing).  
The valid range is 1 to 8 characters. 
Note: The parameter is applicable only to FXO. 
Broken Connection Mode 
configure voip > sip-definition 
settings > disc-broken-conn 
[DisconnectOnBrokenConnection] 
Global parameter that defines the device's handling of calls if 
RTP packets are not received within a user-defined timeout 
(configured by the BrokenConnectionEventTimeout 
parameter). You can also configure this functionality per 
specific calls, using IP Profiles 
(IpProfile_DisconnectOnBrokenConnection). For a detailed 
description of the parameter and for configuring this 
functionality in the IP Profiles table, see ''Configuring IP 
Profiles'' on page 438.  
Note: If this functionality is configured for a specific IP Profile, 
the settings of this global parameter is ignored for calls 
associated with the IP Profile. 
Broken Connection Timeout 
configure voip > sip-definition 
settings > broken-connection-event-
timeout 
[BrokenConnectionEventTimeout] 
Defines the timeout interval (in 100-msec units) after which a 
call is disconnected if RTP packets are not received during 
an established call (i.e., RTP flow suddenly stops during the 
call). 
The valid range is from 3 (i.e., 300 msec) to approx. 2684354 
(i.e., 74.5 hours). The default is 100 (i.e., 10000 msec or 10 
seconds). 
Note: 
  The parameter is applicable only if the 
DisconnectOnBrokenConnection parameter is configured 
to 1. 
  Currently, this feature functions only if Silence
