END TO END TEST BETWEEN GATEWAYS IN AN IP NETWORK

摘要

The present invention relates to methods and arrangements to test end to end relations between gateways MGW1, MGW2 in an IP network IPNW, which method comprises the following steps: 1) reserving call handling resources CH231-CH260 in a destination gateway MGW2; 2) sending data packets RTP/UDP/IP from an originating gateway MGW1 to the reserved call handling resources CH231-CH260; 3) looping back the received data packets RTP/UDP/IP, from the destination gateway MGW2 to the originating gateway MGW1; 4) providing quality statistics for the received data packets, in the originating gateway MGW1.
