Audio stutter when using audio switchboard with narrowband codec (thanks Bogdan Krakowski for the report)

Description (last modified by bennylp)

Audio stutter is observed when configuring pjsua to use audio switchboard instead of the default conference bridge, and when narrowband clock rate is used by the media (for example, play file).

To reproduce:

  1. enable switchboard, by declaring this in config_site.h: 
    #define PJMEDIA_CONF_USE_SWITCH_BOARD	1
  2. run pjsua to stream file 
    $ pjsua --null-audio --clock-rate --play-file pjsua8.wav --auto-play --auto-answer 200
  3. run another pjsua and call the pjsua "server": 
    $ pjsua --dis-codec * --add-codec pcma --local-port 5080 sip:localhost

This was tested on Linux Ubuntu 09.10 64bit.
