Hi all,<br><br>I am new in the FreeSWITCH world and I am not been able to discover how FS can acts as a pure SIP forwarder, sorry. My problem is that I need a kind of B2BUA "in the middle" of the signaling path between my SIP phones and my SIP Proxy. The purpose of this is to get additional features in my VoIP system like CAC, MoH, etc, etc. The first problem I get is I need to forward all REGISTER methods: PHONE -> FS -> SIP PROXY, but WITHOUT changing the Contact header field just adding a Via.<br>
<br>I started with Asterisk due to I have quite experience with it but Asterisk is not able unless you hack chan_sip. FS claims to be a softswitch with SIP router capabilities so, it should be able to do that task. At this stage I am quite confused about the configuration of FS as a SIP proxy and today, I am not completely sure if that is possible to do with FS. Could anyone help me? Is that possible? If that is the case, how could I do it?<br>
<br>Thanks a lot.<br clear="all"><br>-- <br>Arturo Díaz<br><br>Contact me on<br>FWD: 870436<br>Skype: arturo.diaz.almagro<br>
