[Freeswitch-users] How to force the usage of g729 instead of g729b

[Jan Riedinger]

As far as I know the codec strings for g729 and g729b are the same, 
despite these codecs are  not compatible according RFC 3555 (at least 
Cisco is reading the RFC in that way, 
https://supportforums.cisco.com/docs/DOC-3188).
