Ata point-to-point with another ATA

Hi I want to configure two ATAs back to back without using call manager. Where can I find information to do this?

Thanks and regards.

Re: Ata point-to-point with another ATA

Mauricio,

Here is a document that can help you configure ATAs to use H323:

http://www.cisco.com/en/US/docs/voice_ip_comm/cata/186_188/2_15/english/administration/guide/h323/h3288CH4.html#wpxref10281

You can make calls from one Cisco ATA to another Cisco ATA in an H.323 network that does not contain an H.323 gatekeeper.

For one Cisco ATA to access a specific FXS port on another Cisco ATA, you use an IP dialing procedure. The Cisco ATA originating the call must have the following information about the destination Cisco ATA:

•E.164 phone number of the destination FXS port

•IP address of the destination Cisco ATA

To enable the IP dialing procedure, you need to set the IPDialPlan parameter to 1 to instruct the Cisco ATA to look for the destination IP address in the dialed digits.

Example

Cisco ATA X is going to initiate a call to Cisco ATA Y (with the following pertinent information):

•IP address of Cisco ATA Y-192.168.2.112.

•E.164 phone number for the Phone 1 port of Cisco ATA Y-1:5556666

•E.164 phone number for the Phone 2 port of Cisco ATA Y-2:5558888

To call the Phone 1 port on Cisco ATA Y, you would dial 5556666**192*168*2*112#.

To call the Phone 2 port on Cisco ATA Y, you would dial 5558888**192*168*2*112#.
