Hello !

I'm facing two issues with scenarios with INVITE without SDP.

To support this behaviour towards the ingress peer, I activate the following settings:

<param name="enable-3pcc" value="true"/> : per peer ; I also tried with "proxy" instead of "true" but I'm not sure to clearly understand the difference.

I also put this parameter on my internal interface. Everything is working fine except that this setting bypass the B2BUA behaviour for media. I mean that the IP and port for media are no longer my Freeswitch interfaces but the gateways into the core network that finally handle the calls (but the other parts of SDP are the one expected and configured on the Freeswitch interface).

How can I have both support of INVITE without SDP and media proxy active together?

The second issue still start with an in-dialog INVITE without SDP. But instead of re-negotiating the SDP, FS sends the SDP as previous in 200OK. Whereas we expect that FS send SDP with device capability. Moreover, I expect to have the o-line version incremented.

Regards,

Igor.
