The  same  way  as  the  other  function  keys  (except  "HELP"  and  "MENU"),  the  selection  is 
accomplished  for  the  currently  active  channel:  PROG  or  COORD  (the  latter  only  if  license  is 
activated). 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

As can be noticed in the above sequence of screen captures, when in RTP mode the encoding 
algorithms are presented grouped by families (OPUS, G.722,  AEQ-LD,  PCM, G.711,  etc), and 
several  particular  modes  are  available  within  each  family  (A/u  law,  mono,  stereo,  different 
bitrates, sampling frequencies, etc). When a particular mode is selected, successive calls will be 
made  using  that  algorithm,  and  the  remote  codec  must  be  configured  just  in  the  same  way, 
unless "SmartRTP" mode is activated: in this case, the encoding algorithm will be automatically 
notified to the remote audiocodec. 

 

In SIP mode, however, a list of encoding profiles is presented. Each profile is basically a list with 
a name, including one or more precise encoding algorithms, and in order of preference. When a 
unit  calls  another  in  SIP  mode,  it  proposes  this  list,  and  the  first  one  supported  by  both 
audiocodecs will be the one finally adopted. 

 

Management of the existing profiles can only be done by the control software and they remain 
stored  in  the  unit.  The  profiles  are  stored  in  the  non-volatile  part  of  the  ALIO´s  memory.  From 
the front panel of the ALIO the user can only select among a list of stored profiles. 

 

When the user press and hold the "CODEC" key for more than 1 second, an informative screen 
will  show  up  describing  the  currently  selected  codec  or  profile  for  the  active  channel,  without 
making any modifications to it. Whenever a  SIP call  is established, the  indicated codec  will  be 
the one that is actually used. 

 

 

 
3.7.4. "HELP" key. 
 

 

This  key,  that  is  independent  on  the  active  channel,  is  not  following  the  active  channel  and  it 
sends  a  notification  to  the  remote  control  software  provided  that  this  is  in  use.  This  way,  a 
Phoenix ALIO user that requires assistance or has doubts can ask the operator that is remotely 
controlling or monitoring the unit with the "AEQ ControlPHOENIX" software for help. 

 

When the "HELP" key is pressed, a notification will appear on the OLED screen of the ALIO and 
the key will start to flash in red. On the remote control software a pop-up notification will appear 
asking the operator to get in touch with the ALIO user.
