[Asterisk-Users] Record(filename:gsm) very quiet

[Karl S. Katzke]

When I make a recording by setting up an extension with a record() 
statement in my dialplan, the resulting recording plays VERY quietly 
when it's played back over a POTS line, even though it sounds fine in 
the office. Is there any way to increase the gain on in-office 
recordings? I read the wiki and didn't find anything ... is there a 
better way to make these recordings for someone who doesn't have any 
sound equipment?
When the gsm file is playing back, it sounds like it's doing some funky 
slience compression... so when I start to speak, it won't be loud at the 
beginning, but it will slowly get louder. Whenever I pause, the first 
word I say when I start again will be quiet. This is also a problem when 
recording voicemail greetings.
I know that my voice sounds fine when I'm calling out, it's just the 
greetings that are faint.

Any suggestions?

Thanks,
Karl Katzke
