Unimrcpclient does not respect the codecs

[Flavio E. Goncalves]

I'm trying to use G722 to avoid resampling to 16khz. Unfortunately, it does not matter how I try in the client, the system only offers PCMU. I'm trying to call Asterisk with PCMU or G722 and have the leg to unimrcpserver with G722 or another PCM 16Khz. If Asterisk can do the resampling on the fly it is better then doing on the plugin. Currently I'm using the latest unimrcp library and Asterisk 16.
