Solved: ATA Hotline Dialplan toll free number

trevor.stuart · ‎08-21-2024

I'm trying to setup a dialplan in a Cisco ATA192.

It needs to auto-magically dial a 1-888 number when the handset it picked up.

I can get it to dial my own cell phone (10 digital number) without issue. But for some reason when I put the 1888 number in I get an operator stating the number could not be reached.

Below are 2 examples

Works: (P0 <:5555555555>)

Fails: (P0 <:18885555555>)

Incase anyone else comes across this with a simular issue the problem turned out to be our SIP provide requires the ptime to be 20 and the default setting in the ATA-192 is 30.

Took a bit to find the setting that matched this, it was RTP Packet Size. This needed to be 0.020 (default was 0.030). After changing this we can now dial toll free again.
