I think for a lot of customers its as much about commercial support from vendors (basically the same story for all open source vs. commercial solutions), as it is about technical choice.<div><br></div><div>SBCs are seen as a fix all perimeter control for VoIP. I think as we all know there are many ways to solve a problem and architectural solutions for VoIP "interconnect" can also be solved by placing the SBC infront of an infrastructure (perimeter control) or as a border defence behind a proxy/load-balancer.</div>
<div><br></div><div>In some instances its about simplicity. For example I deal with hosted contact Centre environments built around commercial VoIP contact centre solutions from Oracle and CosmoCom, for these it is simpler to place a commercial SBC such as Acme, Sonus or even Cisco "CUBE" facing a carrier SIP trunk interconnect. My customers have the assurance of vendor support and I as a SME, I don't have put a significant amount of time and effort in to supporting an Open Source solution. (Please don't flame me on this last point). Whilst I would like to place Open Source products in this mix (OpenSER/SER, SEMS, Asterisk, Freeswitch, etc) for some of my customers they just don't want to go down that route.</div>
