Can we make codec conversion on gws? For example when a call comes with G.729, then I want to convert it to G.723 on my gw. I use cisco AS5350. And Are there such gateways wchich can make conversion? Thanks
IT IS TASK OF THE GATEWAY.
Codec conversion can be done only by Media Gateways.
There are atleast two gateways that I know and used that do this.
Mera and Sysmaster.
Normally softswitch vendors include a gateway module to take care of the protocol and codec conversion. For example, Nextone makes a softswitch, but it does not convert codecs.
