Hi,
With the current configuration we have, the media is not anchored by by MiVoice business. Right now, the RTP connects from phone to ITSP(Not using MBG). We are trying to configure the PBX to anchor the media so that we don't need to open the phone IPs in VPN connection to ITSP.
If the media anchoring on MiVoice Business is possible, would like to know the conflagration changes required.
From SIP perspective, i want to send the Connection IP in SDP as PBX IP instead of phone IP.
