One of the themes of this blog is how phone conversations can sound much better in VoIP because of wideband codecs. If you have a corporate IT department and a new PBX from a company like Cisco, Avaya, Nortel, Siemens or Alcatel-Lucent, the phones can normally can be configured to use the (wideband) G.722 codec on internal calls. And if you use Skype on your PC, it normally runs with a wideband codec, unless you make a SkypeOut call to a regular phone number.
But what if you are working out of a home office, and you just want your desk phone to sound good, and to use a wideband codec when calling other phones with wideband capabilities? Unfortunately its still a project that can require some technical skills and a lot of time. To make it easier for you, here’s a cookbook explaining step by step how I did it for a particular implementation (Polycom IP650 phone using an account at OnSIP).

Nice work! Provisioning Polycom phones is always tricky the first time you do it.
