Grandstream has a new services GXP-21XX coming out they may work for your. We have been a beta tester and the BLF on these seem to work much better then the GXP-20XX units. I do not have the side cars in stock right now so I don't know how they work with it but you can put at least two for about 112 addtional blf keys.<br />

<br />
We have a user who is putting large call volumes through Asterisk, and<br />
wants to BLF monitor up to 90 extensions. We are struggling to find a<br />
handset that can keep up with Asterisk :)<br />
<br />
1) Is there a handset that will do this?<br />
2) Is there a different (standard) way to send BLF and allow directed pickups?<br />
2a) Or even a handset specific way?<br />
<br />
Asterisk handles the BLF volume fine, even on quite low-end hardware,<br />
but we cannot find any handsets that can cope with it longer term.<br />
<br />
Our test involves about 10 BLF-NOTIFY messages per second to each<br />
handset with a 5-second pause every 5 seconds. This will either crash<br />
or render unusable all of the following combinations:<br />

As Snom phones have a parameter to express a time period during which BLF's SUBSCRIBE messages are spread and sent to Asterisk, I thought Snom phones would handle this load more easily.<br />

Did not try Polycom as they do not do directed pickup and only small sidecars.<br />
Linksys SPA962 with one sidecar is "OK" but is discontinued hardware.<br />
<br />
Help?<br />

Thanks,<br />
