sipXecs includes a stateless proxy called sipXproxy (like SER) and would be the default path when you're doing unattended transfer between local registered endpoints. If you're doing an unattended transfer to a PSTN number however, you need to consider the gateway capabilities and configuration. > I tried Freeswitch for this application, but although it > works, I wasn't impressed on how it rewrites SIP messages > and related SDP; thus searching for a 'pure sip' > implementation that lead me to sipXecs. > > The SBC used in this case can process the REFER; but in > doing so it means the From: and To: headers won't be > rewritten by sipXecs as it's done on INVITEs. > Also, if sipXecs won't intervene in putting calls on/off > hold; what's the purpose of the MOH implementation within > sipXecs? How is a typical implementation supposed to work?

I guess you could say sipXecs is stateful as a whole, but sipXproxy is not, so unless you're dial plan involves Freeswitch, sipXbridge the SIP is mostly passed thru unchanged. > Perhaps an example would be appropriate.

Like the handling > of call transfers and MOH. n, but would be nice. rummage around on wiki, you may find some gems. disclaimer: Not a SIP guy, but I play one on mailing list. _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org List Archive: http://list.sipfoundry.org/archive/sipx-users/
