Hi List i have problem with freeswitch conference example: 1. a company A with PSTN phone number 0822234562 - auto answer machine(IVR) and an extension of company A is from 1000 - 1990 2. a normal PSTN phone : 0833334512 i setup a freeswitch conference room with number is 50000, a moderator dial *2 to make out bound call my network topology: extension A and extension B ------> FS ------SP ------PSTN extension A is a moderator of conference room 50000 entension A calls 50000 and conference is created successfull so there are 2 cases : 1. extension A dial *2 and then enter 0833334512, 0833334512 is added to conference 50000 successfull and everything is fine 2 extension A dial *2 and enter 0822234562, 0822234562 is added to conference successfull The problem is when extension A dial 0822234562, the IVR is played which ask extension A to enter company A's extension, and extension A dials 1000 but it doesnt work because extension A, IVR are in the conference i do debug and see extension A, IVR in a conference and when extension A dial 1000 and see the DTMF event 1 0 0 0 in a conference so that to make it works i do the command line: conference <confname> dtmf <[member_id|all|last]> <digits> conference 50000 dtmf all 1000 is there a way in a case 2: to let extension A dials 1000 when IVR playing to reach company A's extension 1000 and then add extension A, 1000 into a conference 50000 Thank you Ha`
