[cisco-voip] regions, transcoders and bears, oh my!

OK - So this worked like a charm. No additional regions needed! Awesome.

OK, so if all three objects, the transcoder, the iPhone Jabber client, and the UCCx ports are all in the Default region, and I update the MRG(L) of the UCCx ports to include the transcoder, I should be OK then?

A transcoder will be required in the MRGL of the UCCX Port. 

The transcoder should have a device pool who's region relation to the UCCX Port is G711, and to the Jabber client it can be either G711 or G729. Since Region config only specifies the max bitrate between the two devices, if the Jabber client is only offering G729, a G711 region config will still allow the connection between the Jabber client and Transcoder to be G729. 

HTH,

OK, so in fooling around with the Cisco iPhone Jabber client, I've realized that I can put aside the concept of regions and transcoders no longer. The iPhone, when using g729 (in low bandwidth mode) can not communicate to some systems, most notably, IPCCx. 

As far as I understood, regions were used to dictate which codec to use and the transcoder is used to do the translations. 

So, what do I have to do to get the iPhone using G.729 to be able to talk to UCCx (presumably using G711)? 

Is a transcoder enough? If I create the transcoder and put it into an Media Resource Group that both devices can access, should that work? 

I don't understand how I would use regions to classify the iPhone Jabber client, especially since the iPhone Jabber client can dynamically select between codecs depending on bandwidth availability.
