Hello,
o Grygoriy Dobrovolskyy on 06/21/2011 06:17 PM:
Good day, i have some files moved from asterisk with the .gsm
extension, sems has the gsm audio module loaded however he is not able
to stream me the file. I would like to use sems as a simple
announncement player. Asterisk plays that files without any problem.
What should i do to make sems play gsm encoded audio ?
you can either convert the file as was mentioned in another thread, or
use the precoded_announce module, which just streams the already
encoded file. see this .predef definition file for example:
# format:
# codec id;payload name;samplerate;channels;format parameters;frame
milliseconds;frame bytes;filename (full path)
#
# to create e.g. .gsm file:
# sox test.wav -r 8000 -c 1 -g test8k.gsm
#
0;PCMU;8000;1;<none>;20;160;test8k.pcmu;
8;PCMA;8000;1;<none>;20;160;test8k.pcma;
96;iLBC;8000;1;<none>;30;50;test8k.ilbc30;
97;iLBC;8000;1;mode=30;30;50;test8k.ilbc30;
98;iLBC;8000;1;mode=20;20;33;test8k.ilbc20;
3;GSM;8000;1;<none>;20;33;test8k.gsm;
18;G729;8000;1;<none>;20;20;test8k.g729;
