In a method and a system an Internet Protocol (IP) telephony gateway is given a threshold for the performance indicators of the RTCP, and only accepts an incoming call if the present value of the performance indicators are below the given threshold value. By monitoring the quality of ongoing calls, the IP telephony gateway determines whether or not to accept a new incoming call. The method for monitoring the ongoing calls can in particular be the RTCP mechanism, which in some cases already is implemented in the IP telephony gateway, and in which case no new mechanism for monitoring the ongoing calls is required. However, if in some application it should turn out to use another mechanism for monitoring ongoing calls this mechanism could of cause be used in stead or as a supplement. Also, other methods than using a threshold value for accepting/rejecting incoming calls can be used. For example, a function of one or several performance indicating values can be formed. The additional logic required is preferably software implemented making it possible to easily change threshold values, parameters used in the determination process etc. <IMAGE> |
