ATA sipura SPA-1001 dialing very slow

We use a ATA sipura SPA-1001 box to connect our analog phones.
Calling from any phone to the analog phone is fast.
But when we try to call from the analolog phone to any other sip phone it takes approx. 15 sec. before the other phone rings.

Does anyone now what i’am doing wrong?

so when you dial an extension from the analog phone on the ata, you punch in the digits, then wait, then it produces ringing and the other phone rings, correct?

This is because of the dialplan on the ata, or it’s digit timeout. Try enabling ‘live dialing’, incomplete dialing, something like that. Also look at the ATA’s dialplan and see if you can add a thing for a 3-4 digit extension…
