Integrate Cisco ATA 191/192 Analogue Telephony Adapter

01 May 2024

Required steps for integrating a Cisco ATA 191/192 ATA with LoopUp to provide service for fax and analogue devices.

In this article

The below steps provide guidance on integrating a Cisco 191/192 ATA running the MPP (Multiplatform Firmware) with LoopUp to provide service to Fax and Analogue devices.

NOTE: This article has been based on and tested with the Cisco ATA 191, but should also apply to the Cisco ATA 192.
ATA19x-MPP (Multiplatform) devices should not be confused with ATA19x (non-multiplatform) products. The ATA19x product family is purpose-built to seamlessly integrate with Cisco Unified Communications Manager, while it does not provide compatibility with third-party telecom solutions like LoopUp SIP trunks. To ensure proper functionality with LoopUp, it's imperative to opt for ATAs featuring the MPP/Multiplatform designation, as these have been certified for this purpose.

Step 1: Prerequisites

Please note that all steps below assume that the device is online and operational on your local network with the following configuration in place:

  • Default credentials have been changed
  • Static local IP address
  • Accessible from the internet via one of the below methods
    • Direct public IP address allocation
    • NAT/PAT
  • If TLS is to be configured customer provided public certificate will be required

Step 2: LoopUp SIP Trunk Provisioning

  • Navigate to the SIP Trunking Setup article and follow the process to deploy a SIP Trunk with LoopUp

Step 3: Firewall Rules

The below rules will need to be in place to allow the required signalling and media traffic.
