Solution
To support Ascom i75 phones in H.323 v2 mode, different QoS rule is required.
G.711u codec is used with a packetization size of 30ms.
Configuration: Ascom i75 phones use a newer version of H.323 v2 compared to H.323 v1 that supports auto flow detection. We need to delete the default H.323 QoS rules with ID 1 and 2 on Meru controller and create new rules as seen below.
Controller(config)# no qosrule 1
Controller(config)# no qosrule 2
Controller(config)# qosrule 20 netprotocol 17 qosprotocol none
Controller(config-qosrule)# action forward
Controller(config-qosrule)# srcport 5004
Controller(config-qosrule)# tokenbucketrate 9400
Controller(config-qosrule)# avgpacketrate 33
Controller(config-qosrule)# exit
Controller(config)# exit
Controller# sh qosrule
