We got CUBE/SIP trunking deployment in Europe, the incoming leg from provider is G711alaw, however we do have SIP based IVR application that only support G711ulaw. I know DSP/trancoder in CUBE can make such conversion, but I wonder if such conversion can be done without DSP? if so, is it a good configuration example?
The Cisco Unified Border Element (CUBE) supports transcoding for calls that pass through and that require different codecs on the two call legs. Transcoding between various codecs is supported, and CUBE inserts a transcoder based on configuration as well as a mismatch between the codecs negotiated on the two call legs of the calls.
Transcoding requires DSPs to terminate the RTP stream and to decode and encode the voice payload with the appropriate codec. The DSPs used by CUBE for transcoding may be either co-resident on the same router as CUBE or may be located on a separate router platform.
