Here's some more useful info from voip-info.org:
Cisco ATA-18x Series Analog Telephone Adaptor
Cisco's product pages:
The ATA 188 adds a switch with a second ethernet port.
These devices convert two analog phones to IP phones and support the following protocols:
(Note: You will most likely need to download a firmware package to convert the device for the desired protocol.)
(Note: Firmware packages require a contract to download.)
Service Contract Obtaining a service contract directly from cisco can be a lot of fun. When last checked, there's no online registration available, only a page with an email address that's no longer valid. You could try: 1 800 553 6387 option 4 Another option is to order the service contract from a Cisco reseller. CDW and Insight are known to sell maintenance contracts for IP Phones. If you're just looking to obtain firmware for an IP phone product the minimum should be an $8 agreement for one year, chances are you don't need a three year on-site agreement for well over $100. The Cisco part number for the < $10 contract is CON-SNT-CP7960 for the 7960, and CON-SNT-ATA186 for the ATA-186. Note: While trying to get a service contract some have been told that the part number (for either the ATA 186 or 7960) was CON-SNT-PKG1 which runs $60-80. It will take one of the largest technology companies on the planet several days to process your request at which point you'll get a contract number via email. After registering your contract number on their service center website the technically advanced system will tell you a person will validate your contract and grant you access to the firmware files you need within 24 hours. If you buy new (and not from a VOIP provider) you should get at least one free support call. You may be able to convince them to provide you with one free download of the firmware without a service contract. If you purchased the ATA new (not though a VOIP provider,) you get at least one free support call. If lucky and you press them enough, they will give you access to the SIP firmware for download. If you go the contract route, the SmartNet package that applies is part #CON-SNT-ATA186 for the 186 and CON-SNT-ATA188 for the 188. They support the following Codecs:
- G.729, G.729A, G.729AB2
- G.723.1
- G.711a-law
- G.711µ-law
Configuration
A detailed practical explanation how to configure ATA-18x with Asterisk (including password reset procedure): http://www.loligo.com/asterisk/Cisco/ATA-186-guide.v20030628 .txt You'll need to setup a TFTP server for firmware upgrades. The firmware package should include detailed instructions on how to configure the unit. If you opt for the TFTP configuration route, the basic steps are:
- Edit the text configuration file
- Use the cfgfmt.exe tool to convert the file to binary format named the MAC address (no caps)
- Upload the binary file to the TFTP server
- Reboot the device
WebConfiguration
For Remote purposes, small installations or quick config changes, it's easier to configure the ATA 186 over the integrated Webserver.
To find out the the IP address of the ATA 186 pick up a connected phone, press the button on Top and Dial "21#". The ATA 186 now tells you it's actual IP address. Open a webbrowser an point it to the told address and ad "/dev" to the end.
Example: The ATA tells you IP 192.168.0.15 then point your Browser to "http://192.168.1.15/dev" and you can quickly change some parameters without needing to reflash it.
Turning off silence suppression
If you're getting these warnings during a call from the ATA: NOTICExxx : File rtp.c, Line 264 (process_rfc 3389): RFC3389 support incomplete. Turn off on client if& nbsp;possible Then you have to login to the ATA configuration page and change "audiomode" to "0x00140014" Distinctive ring
Set variable ALERT_INFO to change the ring cadence. Example:
exten => 5555,1,SetVar(ALERT_INFO=Bellcor e-dr1) ; possible values are Bellco re-dr1
exten => 5555,2,Dial(Sip/5555) ; ;; ... Bellcore-dr5
Cancel CDP broadcasts
Cisco devices are quite friendly. When you hook them on the wire they will broadcast CDP
traffic (Cisco Discovery Protocol) trying to locate other cisco devices. You may not need the extra traffic. (if the only cisco device you got is your ATA 18x) Here's how to proceed:
This can be done by selecting IVR menu 323, and then entering in the value 106. If you are configuring this field via the Web Interface, then configure the hex value 0x6A in the OpFlags field. This will disable, CDP Discovery, 802.1Q tagging, and it will prevent the ATA from requesting option 150 in its DHCP request. Incidentally, some DHCP servers will not respond to a client that requests an Option unknown to them, which may lead to the ATA not being able to acquire an IP address.
Call Pickup
It seems that the logic for handling special calling features (vertical service codes) intercepts the standard *8 Asterisk call pickup code. One option is to change the pickupexten in features.conf to a regular extension number. My extensions range from 201-219, so I picked 200 as the pickup extension for example.
