Ini File for Audiocodes M1k

This is a Great file to upload into the Gateway to make a standard starting point for all installations. The Things in Bold and highlighted should be changed once the ini is uploaded into the gateway. They should be changed to information about your own environment

To use this file copy and paste the below code into notepad and save the file as an ini
It is always best to upload the file first and then modify it in the gateway.

Sip Test Phone for Sip Gateways

Here is a great way to a Sip Test Phone to make calls from inside the Audiocodes Gateway.

Here is the Situation you want to make some test calls through the Audiocodes/ Dialogic Gateway out to a phone or out to the PSTN.
Here is what i just used to make calls to test my Trunk Setting on an install
the only catch is that the Xlite Sip Phone calls using UDP not TCP
Do not download the demo version of Xlite download the full version

Click the drop down arrow on the top of the App
Go to sip accounts
Click add

Display name is the Caller ID
User name is the DID you want to show for the Caller ID it does not have to be a real number on the PBX at all or it could be a number that is already in use so you could impersonate a user
Domain is the IP address of the Gateway
Uncheck the Register with domain and receive incoming calls

Can't log into OWA

if you can't log into owa here are some things to check



  • Certificates

  • Permissions

  • Log on challenge is using NTLM

  • Has the Directory name of OWA been Changed?

Do not change the directory on OWA as it is integrated into the AD as well. If you need
to change the OWA director Please Read this Microsoft Article.

Cisco Call manager 5.x & 6.x

The Microsoft document That explains how to set up the call manager systems is missing one part if you want to have the traffic come through on TCP rather than UDP for Unified Communications. This is important to remember to change this setting in the call manager system. during the setup of the new Sip trunk other wise there will be a situation like the following

If you call into an Auto attendant or Subscriber access the UM role on that is a part of exchange will not pick up it will either just ring or it will ring and answer to "Dead Air"

To fix this problem you will have to set the Traffic To TCP rather then the Default UDP.
