[pjsip] dtmf across conference bridge. pjsip v1.0 rc1

[David Clark]

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
