Codec gsm fail freeswitch

friends, does anyone use gsm codec in astpp? I can’t activate this codec, it doesn’t show up in the freeswitch codec list. I managed to add the opus, does the gsm have to be installed? Someone help please?
thanks and regards

Check if you have mod_spandsp module loaded. If not then load that and that will enable GSM codec. Ideally that is enabled by default.

Hello Samir, this is the problem, neither gsm and g722 are available to use with astpp, as spandsp was taken from debian 10 and requires manual compilation, could you update the installation script or show us how to recompile manually?
Thanks and Regards

@dbbrito this might help
