Audiocodes MP118 8 FXO early media to Freeswitch SIP extension

I have one Audiocodes MP118 8FXO media gateway, between PSTN and internal SIP PBX Freeswitch, when calling from PSTN to IP, in this case, FXO automatic dialing ext 5001 on SIP server which is supposed to play IVR prompt, the problem is 1) many times when PSTN calls get answered some random media inserted before the right IVR prompt

2) some times the IVR prompt got cut off for the initial part

Audiocodes MP118 setup with not registering with SIP server, early media disabled. I have no single issue when calling from any SIP phones inside the network to the ext 5001 which is a main IVR.

could you please shed some light on this as you guys are Audiocodes experts?
Thanks,

Chris Chen

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.

How to reset MP 124


It's - literally - right in front of you.

There is a pinhole on the front of the device; to the left of the display where it says "Channels."

AudioCodes MP-11R/2FXS


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)

If you need the manual (and it never hurts ;-) here is the link:

Hi, I am using Audiocodes MP-118 FXO too
Man, check the Reverse Polarity.

1st.- Go to Protocol Management
2nd.-Go to Advance Parameter
3rd.- Go to General Parameter
4th.- Go to Enable Polarity Reversal and select ENABLE
5th.- BURN and RESET

You have FAS calls, because Reverse Polarity is disable.
