I haven&#39;t had a chance to actually test this config in lab but I will in the coming days. One issue I see is when we use registered endpoints, such as ATAs, behind NAT: bypass_media fails in this case because FS uses the private network IP instead of the public network IP in SDP. In case of a large number of such registered endpoints, we may have to make them talk with an FS-RTP server directly because they don&#39;t use bypass_media while FS-SIP does. Can we use bypass_media_after_reinvite for them or would it have the same behavior of using private IP? Or we could use proxy_media; which is not want we really want to do but could work in a pinch. Or is there a better way to combine bypass_media with NAT&#39;ed endpoints?<br>

<div style="word-wrap: break-word;">Mike,<div><br></div><div>You&#39;re right, it can be achieved with SIP now that I think a bit more about it.</div><div>The idea was to allow adding multiple media gateways when required, so the media gateways should not be facing the carriers as some of them do SIP-filtering, but should only be advertised in the SDP.</div>
<div><br></div><div>So SIP-only boxes (doing bypass-media) should face the carriers to handle the trunking.</div><div>In the middle, we would then have the media gateways, doing SIP and mostly RTP.</div><div>But I guess we dont want customers to register and to send calls to a media gateway, so we need another set of SIP boxes on the other side, doing bypass-media also.</div>
<div><br></div><div>So it would like this:</div><div><br></div><div>                             ------sip-----FS-RTP-1-----sip------</div><div>FS-SIP-Internal-1 ------sip-----FS-RTP-2-----sip------FS-SIP-External-1----sip-----Carriers</div>

<div><br></div><div>Thanks to bypass-media, the RTP streams would go from customer to FS-RTP-x to Carriers, and reverse.</div><div>And I don&#39;t see any reason why the same set of FS-SIP boxes could not be used for both internal and external borders.</div>
