[asterisk-users] Sangoma FXO EC vs Rhino FXO EC

[Rod Montgomery]

Michael,

I'm very interested in helping you resolve any and all trouble you have with Digium products. The experience you describe with our products not typical, so I'd like to address them specifically.

My comments are inline:

Yes, any decent hardware echo canceler would provide a significant improvement over mg2 on difficult trunks. As noted already in this thread, Digium offers software-based High Performance Echo Canceler (HPEC) and hardware-based echo cancellation options. They're well worth the incremental expense when you need reliable, high-quality echo cancellation. 

Evaluating a Digium interface without hardware echo cancellation versus Sangoma with hardware echo cancellation isn't really an even comparison, is it?  I invite you to evaluate similarly equipped interfaces.  I'm confident that you'll change your opinion about Digium's product performance.

The TDM400 does not support on-board echo cancellation; the TDM410 does. For low density analog, the TDM410 is an outstanding solution. Voipsupply's website catalog isn't exactly up to date, but there are plenty of other reputable resellers that would be eager to help you with the latest interface technology; just visit <URL:http://www.digium.com/en/wheretobuy/>.

However, it sounds like you're reselling these to end users: have you considered joining Digium's reseller program? You would enjoy many benefits that would smooth your path to success, including special pricing with an authorized Digium distributor. See <URL:http://www.digium.com/en/ecosystem/resellers/> for more information.

That's troubling... even before the recent announcement of an expanded warranty as part of our Exceptional Satisfaction Program, all Digium interface cards carried a two year warranty. There's no way we would have turned you away at 13 months. Or 15 months, or 18.

I went to investigate this and couldn't find any record of you contacting Digium Technical Support. Did you use a different company name? Perhaps a different representative of your firm contacted us. Are you confusing your e-tailer's limited one-year return policy for Digium's warranty?  Even if your webstore refuses a return, Digium will honor the product warranty.

Truly, the tired old reasons to avoid Digium -- IRQ-related headaches, "motherboard incompatibilities," lack of hardware echo cancellation on analog and single-span T1, etc. -- just don't stand up any more. Digium's Exceptional Satisfaction Program signals a new standard of quality and reliability in the telephony market. And our Technical Support team has a great track record, often mentioned on this list. We're ready to work with you to make your Digium Asterisk deployments a resounding success.

Sincerely,
rm
