[Freeswitch-users] G.729 Passthrough question

Hi Guillermo,

Are your 900 calls handling surveys by DTMF? If so I would be interested 
to hear your experiences with the reliability of that. We still see so 
many quirks with the handling of DTMF in VoIP applications that 
experiences with such a large deployment are of value. Especially ones 
using low bit rate codecs like G.729, where audio DTMF can be quite 
troublesome.

Regards,
Steve
