Ok caller A calls in Caller B is called with pjsua_makecall. A two way bridge connection is made caller A to Caller B. If caller B hits a dtmf caller A hears it. IF caller A hits a dtmf caller B does not hear it. Switch phones and you get the same result. Any ideas what might cause this? I do know that pjsip sees the caller A dtmf because on_dtmf_digit is called with the correct digit. Thanks, David Clark
