SIP Line configuration

In a SIP Dialer configuration, there can be a perceived delay between the time the caller completes his or her greeting and the agent is connected to the call. This delay can have significant impact on live speakers connections. In general, it is recommended that TCP be used with SIP lines configured for Dialer. If UDP is used, it is recommended that the Reinvite Delay be reduced from its default value of 750 to 50 ms for Dialer configurations.
