Hi All, I am using Freeswitch 1.6 with CentOS 7.2. When I am making outbound call from Freeswitch using extension on Softphone/Ip Phone then I am able to send all DTMF only * not able to send. When I have to send * DTMF then I am pressing two time * then its only working. So whenever I have to send 8 DTMF then I need press two time * from softphone/IP Phone. *On CLI I am getting only one like when pressing one time * after that nothing getting on CLI.* 2016-07-29 18:01:42.680250 [DEBUG] switch_rtp.c:6147 RTP RECV DTMF *:800 *When I am pressing two time ** 2016-07-29 18:01:42.680250 [DEBUG] switch_rtp.c:6147 RTP RECV DTMF *:800 2016-07-29 18:01:42.880250 [DEBUG] switch_rtp.c:6147 RTP RECV DTMF *:640 2016-07-29 18:01:42.880250 [DEBUG] switch_channel.c:488 RECV DTMF *:640 2016-07-29 18:01:42.880250 [DEBUG] switch_ivr_bridge.c:470 Send signal sofia/external/525585262618 [BREAK] 2016-07-29 18:01:42.900250 [DEBUG] switch_rtp.c:4610 Send start packet for [*] ts=36960 dur=160/160/640 seq=23645 lw=36960 2016-07-29 18:01:42.920250 [DEBUG] switch_rtp.c:4509 Send middle packet for [*] ts=36960 dur=320/320/640 seq=23646 lw=37120 2016-07-29 18:01:42.940250 [DEBUG] switch_rtp.c:4509 Send middle packet for [*] ts=36960 dur=480/480/640 seq=23647 lw=37280 2016-07-29 18:01:42.960250 [DEBUG] switch_rtp.c:4509 Send end packet for [*] ts=36960 dur=640/640/640 seq=23648 lw=37280 2016-07-29 18:01:42.960250 [DEBUG] switch_rtp.c:4509 Send end packet for [*] ts=36960 dur=640/640/640 seq=23649 lw=37280 2016-07-29 18:01:42.960250 [DEBUG] switch_rtp.c:4509 Send end packet for [*] ts=36960 dur=640/640/640 seq=23650 lw=37280 2016-07-29 18:01:42.960250 [DEBUG] switch_rtp.c:4462 Queue digit delay of 40ms 2016-07-29 18:01:42.960250 [DEBUG] switch_core_session.c:1062 Send signal sofia/external/525585262618 [BREAK] Please help. -- Thanks & Regard Uday Site:- www.shareyourknowledge.in Mobile:- +91-9377579349
