<html><head></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Hi all,</div><div><br></div><div><div>I would like to setup a B2BUA SBC on our OpenWRT based router to work with our sipX PBX. Very simple requirements:</div><div><ul><li>authenticate outgoing calls for our ITSP</li><li>preferably enforce negotiation of G729 due to limited bandwidth</li><li>no need to relay RTP, just let it get passed through from the phones to the ITSP directly</li><li>possibly register with our ITSP for inbound calls which would be sent to the PBX (unlikely to be used, but nice as an option)</li></ul></div><div>An advantage would also be that it can be started and stopped, etc in line with the state of the Internet connection rather than waiting for a timeout if the Internet is down. The PBX would then automatically route calls via the PSTN SBC.</div><div><br></div><div>I've looked at the B2BUA documentation but it uses two modules that don't appear to be available in OpenWRT: b2b_entities and b2b_logic.</div><div><br></div><div>Is it possible to get opensips to act as a B2BUA with the available modules listed below, possibly with an external script. The version is given as 1.5.3-1 if that affects anything.</div><div><br></div></div><div apple-content-edited="true">
