The update has not been released publicly, but you can get it by contacting Syspine Technical Support at 800-713-3386.

If you’re using  a Syspine base unit with the built-in ATA, and you’re using Aastra phones, you’re likely to hear sporadic DTMF tones on the phones.  The person you’re speaking to won’t hear this problem, and internal calls or calls via a SIP trunk won’t exhibit this behavior.

After speaking with Syspine we’ve found out that the problem is being caused by the Syspine doing out-of-band signalling via DTMF, which the Aastra phones are interpreting as standard DTMF tones which are then played through the handset.

The good news is that a fix is being worked on.  Syspine and Aastra engineers are collaborating to resolve the issue.  I’m told that it will be a couple  of weeks before the fix is released, in the form of a firmware upgrade for the Syspine ATAs.

We’ll keep you posted and we’ll provide a link to the fix once it’s available.

You can download it (along with firmware for their phones) on their download page here.

We recommend that whenever you install updated ATA module firmware, you also update the Syspine Module Page firmware to the latest version (available from the same download location).
