• In the IOS 15.1 interoperability guide, hardware MTPs support only G.711 a-law and G.711 u-law, and only one codec is supported for each MTP profile. in context
• The device name given in the IOS associate profile ... register command must match the device name configured in Unified CM; otherwise the DSP farm profile is not registered to Unified CM. in context
