I have a SpectraLink 8440 wireless phone connected to a 3300 running MCD 4.2 (load 10.2.0.26_2). I can get the call to connect and get 2 way audio on the far end (PSTN and MiNet phones), however I cannot get audio back on the SpectraLink. I also have another SIP wireless phone that works fine (they share a SIP profile).
Has anyone used one of these before or have any tips on making it work? The handset itself has what seems like 1000 options in it.
