Hello, Could you help me in using paoffhook? I shell pass the call_id as argument to the paoffhook? Where comes this callid from? in mod_portaudio::ringing the callid is empty in channel_on_init() function there is a debug log snprintf(buf, sizeof(buf), "BRRRRING! BRRRRING! call %s\n", tech_pvt->call_id); This callid is empty here too! I think the call is not added to the global call hash... details: http://pastebin.freeswitch.org/147 Thanks, Tamas
