Fw: [Asterisk-Users] IAX Bandwidth Question

[Jay Tyndall]

Subject: Re: [Asterisk-Users] IAX Bandwidth Question


 Hi,

 I have changed the codec to lpc10 (I see what they mean by Mr. Roboto!!)
and
 the ping times generally dont go over 300ms.
 It seems very odd that GSM saturates the link.

 I would love to give g.723.1 a try but have no idea where to get the
proprietary codec... can anyone help?

Thanks
 Jay
