[Freeswitch-users] How can I keep the A-leg from establishing early media (and playing ringback in-band) until after the B-leg answers the call?

[Jason Jeffords]

Hi Giovanni,

Our case 3 test was actually being bridged to a SIP endpoint (not in a
conference, although
this probably should not matter).

We tested two type 3 cases:

1) Skype to FreeSWITCH Skype bridged to an extension of a registered SIP
phone
2) Skype to FreeSWITCH Skype bridged to an outbound call through a PSTN
gateway

In both cases we are transiting FreeSWITCH, not terminating on it (could
there be a
race condition when doing signaling coordination to remote SIP endpoints,
not FreeSWITCH
itself?).

When we terminate Skype calls on FreeSWITCH this works (case 2).  It also
works
for outbound Skype calls (case1 - SIP to FreeSWITCH, FreeSWITCH Skype to
Skype).

Also, we are running the very latest (well, as of this morning) git version,
so that
may introduce one more variable (if you are running an older version).

Thanks for your help,

Jason
