I reset my Audiocodes MP202 B 2FXS. Then I connected that to my PC and I could see the gateway Ip as 192.168.2.1. When I tried that Ip in the browser I got the MP20X management console. But what is the user/password to go inside? I tried admin/admin but not working. Please help.

Step one turn on PC directly connected to ModemsbSB6121 without Wi FI router being involved.
Step two go to Command prompt type in ipconfig (press enter)
Step three note IP address of default gateway and ip address issued to P.C.
Step four type in default gateway address into browser and log into Modem.
Step five look for DHCP Server and allocate IP addresses from at least 50 for example 192.168.0.50 starting ip lease ending ip lease 192.168.0.254
Step six connect Wi Router to P.C. via ethernet cable only - remove ModemSB6121
Step Seven shutdown and restart p.c
Step Eight go to Command prompt type in ipconfig (press enter)
Step Nine note IP address of default gateway and ip address issued to P.C.
Step Ten type in default gateway address into browser and log into Wi Fi Router
Step Eleven Change IP address on Router to 2 as example 192.168.0.2. (it has to match in that modem device would have been 192,168.0.1)
(if it was 10.0.0.1 make wi fi 10.0.0.2 make sure subnet mask is the same like 255.255.255.0)
Step twelve Change DHCP Server to off
Step Thirteen may need to set default gateway to MODEM IP address for example 192.168.0.1
Step Fourteen plug modem router into Wi Fi router may need to plug into WAN port on WI FI router .
Step Fifteen shutdown and Restart Computer
Step Sixteen go to Command prompt type in ipconfig (press enter)
Step Seventeen type in PING 192.168.0.1 (if this is modem IP address and default gateway IP addess)
All this above is to avoid IP address conflicts or mismatching
Subnet mask should be 255.255.255.0
either it uses 192.168.0.1 or it uses 10.0.0.1 make sure Wi FI router is set to different address to Modem Router.
I suspect either a clash occurs or your P.C gets a different IP range from ther WI FI DHCP server.
Happy troubleshooting !

Your Connectivity may be on Wifi or Lan, ping the gateway and verify gateway IP is up and running if not then try to manually assign the IP to the system and try ping and if there is any proxy Please also remove the proxy from the internet settting and if still problem.Then reset the modem and then also set the IP of your system 192.168.1.2 and access the by default IP 192.168.1.1 and configure the acces point

There is probably a reset button somewhere on the device, it is probably a small pinhole that you put a paper-clip into the reset.
If it has its own http web page, there is likely a reset to factory defualts option.

The ip of the computer connecting to it should not change.
On a computer connected to it, open cmd start>run then type in cmd, and type 'ipconfig'.
It will display details about your connection. Where it says 'default gateway' is the ip of the device.
You could try to put the ip in your browser and see if the device has a web page.

go to start run and type cmd and press entere. A black screen shows up. type ipconfig then press enter. You may have to scroll up but the number next to gateway is the ip address you need to type into your browser to get acess into the router.

In the fast track guide there will be IP's listed. find the one for the device you are configuring, set you computer or laptop to an IP that is in the same range and connect via your broswer by IP.

Example:

Audio Codes IP and mask: 10.1.10.10 255.255.0.0
Set your pc IP to: 10.1.10.11 255.255.0.0

In the address bar of your browser type in 10.1.10.10. You should get a window asking for user name and password.

The easiest way (if enabled) is to use the voice menu as if you would assign a new IP to the device.

1. Connect a telephone to one of the FXS ports. Lift the handset and dial ***12345 (three stars followed by the digits 1, 2, 3, 4, 5).
2. Wait for the 'configuration menu' voice prompt to be played.
3. To change the IP address, press 1 followed by the pound key (#).

• The current IP address of the gateway is played. Press # to change it or hang up if you don't want to change it.
  
• Dial the new IP address; use the star (*) key instead of dots ("."), e.g., 192*168*0*4 and press # to finish.
• Review the new IP address, and press 1 to save it.

Of course you can try the default IP of 10.1.10.10 if the device is set to it's default standards.

If not, you can try a network scanner like angryip (link) or network scanner (link) - this might take a long time, since the IP can be virtually anything.

If you have physical access to the device, you can also use a straight RS-232 cable to connect the AudioCodes to your PC and use HyperTerminal to connect (Baud Rate: 115,200 bps (MP-124), 9,600 bps (MP-11x), Data bits: 8, Parity: None, Stop bits: 1, Flow control: None)

Connect using Lan Cable
be sure to enable java on your Browser.
Use ONLY IE: some router refuse other browser.
SET your PC on a static IP address on SAME subnet as your router (but of course different IP).
If subnet concept is NOT clear to just just ask here.
When connected with router (on Lan Cable) check every setting (WPA-PSK) TKIP key, Broadcast / Channel etc.
You can also disable every WLAN protection and restore it later.
Activate WLAN connection WHEN you are STILL connected.
Last but not least: SET your DNS IP address = your gateway IP (router)

1 ) Check if IP address is the correct address of your Gateway.
Check if you can ping.
Be sure you have your Java enabled
Some router requires a specific Browser (IE6 or IE7) and cannot respond to different browser.
Be sure to remove any Java protection from your Browser.
Check with user manual if IP address requires also a specific port number ( 8080 or other).
Be sure to Connect Router using Lan cable
2) Change your PC IP setting to same subnet as your router
Control Panel / Network settings / properties of TCP/IP define an IP address and a subnet mask compatible with Router as gateway.
3) If you are not sure of Router IP address use reset button on router back to factory default; use this to configure router.

Hi, man.
There are many things to consider in this type of application.
when calling from PSTN to IP using analog lines from time to time you will have this type of event, I suggest working with H323 protocol, this will tone down a bit your problem.
If you want optimum performance, you should use a DID with the channels you need and address to your PBX SIP FreeSwitch. The DIDs are cheaper and are digital which eliminates random connectivity problems in the incoming call.
Once you have directed the DID you tell your server to transfer the call to the IVR using your internal dialing plan.
