Hi, There are a whole bunch of .gsm, .ulaw, .wav files in /var/lib/asterisk/sounds/ within asterisk. Is there any ways to create a custom recording by concatenating these available files?
Say 1-for-am-2-for-pm.gsm + thanks-for-calling-today.gsm +... to make up a custom sentence to be played back to the callers. Also, I tried to converting a gsm file to wav format but end up with very low volume - too low it's not usuable. Any ideas on how to normalise a wave file in Asterisk? Thanks in advance, Richard
