Fix Sipura VOIP ATA Adapter interdigit dialing delay

2 common problems encountered by people who have purchased Sipura VOIP adapters such as the Sipura 2000 (2 VOIP lines) or Sipura 3000 (combined VOIP/PSTN failover) is that these devices expect you to dial a phone number quite quickly with little delay between each digit, and then take several seconds to actually dial the number once you’ve entered all the digits.


If you forget a digit and take too long to enter the next digit the Sipura aborts the call. To fix this adjust these Regional settings in the Sipura admin area:

Interdigit Long Timer: Specifies the default maximum time (in seconds) allowed between dialed digits, when no candidate digit sequence is as yet complete.

Interdigit Short Timer Specifies the default maximum time (in seconds) allowed between dialed digits, when at least one candidate digit sequence is complete as dialed.

I have the Interdigit Long Timer set at 10 and the Interdigit Short Timer set at 5.

To Dial a number faster: You can press “#” after entering the whole phone number or you can change the dialplan, so it has the exact pattern of the numbers you are dialing.
