g711 to g722 transcoding causing distortion on Polycom IP6000 handsets
This is almost certainly more of a Polycom issue than a FreeSWITCH one but I'll mention it here on the offchance that someone else has experienced the following: Loud G.711a calls that are being transcoded to G.722 are massively distorted on Polycom IP6000 handsets and on all other handsets the call just sounds loud and isn't distorted. This is most common in conference calls where callers are using a mixture of codecs. If I disable G.722 the Polycom sounds fine even though the G.711a call is still too loud and if I lower the volume of the conference the distortion still happens. So, has anyone else experienced this and if so, did you find a solution? Regards, Dan Lane
I'm going to guess you're using 1.0.4? /b On Mar 8, 2010, at 1:42 PM, Dan Lane wrote:

I am, was this fixed in 1.0.5? While I have 1.0.5 boxes (which identify themselves as 1.0.trunk) coming out of my ears the Polycoms are all overseas and in-use so getting them temporarily connected to a 1.0.5 box is troublesome.
It was a bug in spandsp codecs thats been fixed for sometime. /b On Mar 8, 2010, at 2:46 PM, Dan Lane wrote:

Thanks for the quick feedback... I'll try and get that box upgraded ASAP :)
