Nice article, just shows that the BeThere has no place in the real world. No seriously, thanks, I've been working with OPX for years without knowing what the acronym stood for - always wanted to know - but never cared enough to ask.
Does RACE run voice over ATM or VoIP.
"Finally, there is an emerging class of products known as IP PBXs. These use VOIP routing to match phone numbers to IP destinations, replacing centralized PBX circuit switching with end-to-end packet switching. Conventional phones and PBXs are attached to router or server ports, or IP telephones are attached to network workstations."
Your RACE products can't do that - routing to the VPN or local PBX is essential.
"Packets, frames, and cells come in all sizes, and on slow links larger ones will delay the voice transmission. So all voice technologies reduce the size of the data element: IP packets are fragmented, while other protocols are limited to a smaller MTU (maximum transmission unit) size.
"Another source of jitter is network congestion caused by bursts of data traffic. Vendors offer various COS solutions to combat this and keep voice flowing, such as proprietary queuing, WFQ (weighted fair queuing), IP precedence, and RSVP (resource reservation protocol). Still, congestion is more of an issue on WAN links. Net managers could help themselves here by following up with the vendor. "
What does that does that say for RACE's ESP technology? If it's only an issue over LANs then what problem did Ben solve?
"But voice-over-data equipment also adds latency: End-systems take time to digitize voice signals, and they must add "dejitter" buffering delay to compensate for any variable delay remaining in the system. That can add up to as much as 80 ms.
Oops, another probelm for RACE they need to decode and redigitze voice if they need to send it over a H.323 compliant network - unless they have a proprietary protocol - but then your stuck with their crap at all the nodes.
"But even more savings are possible with the voice-over-data/PBX integration application. Here, the number of user connections can grow (or be oversubscribed) far beyond the available channels on the PBX. The voice-over-data network attaches to a trunk-side interface on a central PBX, but the phones in remote sites are connected to FXS ports on voice-over-data equipment (see Figure 2, again)."
But all the main PBX manufacturers have their own crap - RACE's stuff just gets in the way and adds the redigitization problem - see above. And so on.
