Well we had pretty good prices on Digium but still the A500 models
with EC chip are a bit more expensive for the same port density.

Subject: [sipx-users] Patton smartnode 463x : is 25ms echo cancel
tail enough ?
Hi,
Are some of you using Patton smartnode BRI
Hi,
Are some of you using Patton smartnode BRI gateways ? I see the
hardware EC is only 25ms (PRI one have 128ms).
Is this tail long enough for PSTN connection under regular usage ?
Thanks for your feedback
regards,
Gaetan
