A method comprising: generating, by a telecommunications system, an initial route table for a predicted traffic, the predicted traffic including, per destination in a given period of time, the number of predicted calls, wherein the generating is based at least in part on: I. a first threshold value of a first quality metric for the predicted traffic, wherein the first quality metric is based on a ratio of answered calls to call seizures, II. a second threshold value of a second quality metric for the predicted traffic, wherein the second quality metric measures call duration per answered call, and III. the predicted traffic; routing, by the telecommunications system, a plurality of calls according to the initial route table; analyzing, by the telecommunication system, if any one of a first, second or third condition exists: the first condition being when the first quality metric for the predicted traffic exceeds the first threshold value for every route in the initial route table; the second condition being when the second quality metric for the predicted traffic exceeds the second threshold value for every route in the initial route table; and the third condition being when the predicted traffic for the given period of time is allocated to the routes in the initial route table; generating, by the telecommunication system, based on analyzing the first, second or third conditions, an adapted route table by decrementing the first threshold value by a first predetermined value, and decrementing the second threshold value by a second predetermined value; and routing, by the telecommunications system, another plurality of calls according to the adapted route table. generating, by a telecommunications system, an initial route table for a predicted traffic, the predicted traffic including, per destination in a given period of time, the number of predicted calls, wherein the generating is based at least in part on: I. a first threshold value of a first quality metric for the predicted traffic, wherein the first quality metric is based on a ratio of answered calls to call seizures, II. a second threshold value of a second quality metric for the predicted traffic, wherein the second quality metric measures call duration per answered call, and III. the predicted traffic; I. a first threshold value of a first quality metric for the predicted traffic, wherein the first quality metric is based on a ratio of answered calls to call seizures, II. a second threshold value of a second quality metric for the predicted traffic, wherein the second quality metric measures call duration per answered call, and III. the predicted traffic; routing, by the telecommunications system, a plurality of calls according to the initial route table; analyzing, by the telecommunication system, if any one of a first, second or third condition exists: the first condition being when the first quality metric for the predicted traffic exceeds the first threshold value for every route in the initial route table; the second condition being when the second quality metric for the predicted traffic exceeds the second threshold value for every route in the initial route table; and the third condition being when the predicted traffic for the given period of time is allocated to the routes in the initial route table; the first condition being when the first quality metric for the predicted traffic exceeds the first threshold value for every route in the initial route table; the second condition being when the second quality metric for the predicted traffic exceeds the second threshold value for every route in the initial route table; and the third condition being when the predicted traffic for the given period of time is allocated to the routes in the initial route table; generating, by the telecommunication system, based on analyzing the first, second or third conditions, an adapted route table by decrementing the first threshold value by a first predetermined value, and decrementing the second threshold value by a second predetermined value; and routing, by the telecommunications system, another plurality of calls according to the adapted route table.
