Hi all, when i run pjsua.exe as two different clients and try to send dtmf to each other by following steps: - run pjsua.exe - type in(on both clients): Cp - type in(on both clients): PCMU 200 - type in(on one client): # - type in(on one client): 123 then i get the following message:pjsua_app.c Unable to send DTMF: Remote does not support RFC 2833 (PJMEDIA_RTP_EREMNORFC2833) [status=220107] Could someone tell me what goes wrong here, and how to fix it? thanks in advance! -Jessica _________________________________________________________________ 新年换新颜，快来妆扮自己的MSN给心仪的TA一个惊喜！ http://im.live.cn/emoticons/?ID=18

Hi, Please check whether macro PJMEDIA_RTP_PT_TELEPHONE_EVENTS & PJMEDIA_RTP_PT_TELEPHONE_EVENTS_STR (payload type definition for DTMF) are set to non-zero, and then make sure there is rtpmap "telephone-event/8000" in the SDP negotiated. The macro is set to 101 by default in pjmedia/config.h.
