[Freeswitch-users] Multiple Soundcard Channels

[Repost - apologies to all for my earlier unintentional hijack.] Can I start multiple instances of mod-portaudio? I would like to have multiple channels from my alsa-compliant soundcard but I can't find a way to run multiple channels in FreeSWITCH. I am connecting to a PABX and need to bridge calls. Am I missing something obvious? Thank you, Erik
