The Nortel/Avaya 2245 Wireless Gateway is a essentially a protocol translator running Linux. The wireless gateway bridges between the Nortel/Avaya OEM’d SpectraLink wireless handsets (6120, 6140) which utilize SpectraLink Voice Priority (SVP) and the Avaya Call Server 1000, Signaling Server, and Voice Gateway Media Cards running UNIStim.
Unfortunately the 2245 doesn’t ship with the correct QoS configuration and instead must be manually configured in order to attain the proper DiffServ/QoS markings between the wireless telephones (WT), the 2245 and the call server.
From the main menu of the 2245 select SVP-II Configuration, then select QoS Configuration and modify the options as depicted below;
