Configuring Voice Configuring Voice Services 6 Feature Description Signaling Hook Flash Event The SRP can signal hook flash events to the proxy during a connected call. This feature can be used to provide advanced mid-call services with thirdparty-call control. Depending on the features that the service provider offers using third-party-call-control, the following ATA features may be disabled to correctly signal a hookflash event to the softswitch: • Call Waiting Service: Refers to the call waiting serv parameter in the Line pages. • Three Way Conference Service: Refers to the three-way conf serv parameter in the Line pages. • Three Way Call Service: Refers to the threeway call serv parameter in the Line pages. You can configure the length of time allowed for detection of a hook flash using the Hook Flash Timer parameter on the Regional page. See Regional Page, page 136. Configurable Dial Plan with Interdigit Timers The SRP has three configurable interdigit timers: • Initial timeout (T)-Signals that the handset is off the hook and that no digit has been pressed yet. • Long timeout (L)-Signals the end of a dial string; that is, no more digits are expected. • Short timeout (S)-Used between digits; that is after a digit is pressed a short timeout prevents the digit from being recognized a second time. See Configuring Dial Plans, page 102 for more information. Cisco SRP500 Series Services Ready Platforms Administration Guide (SRP520 Models) 93
