Configuration Guidelines H.323 And SIP


H.323
Fixed IP address (Your IP address never changes)

  1. Make sure the IP address you use has been added to your MAXATEL Phone Account.  If you did not add this address while setting up your account, then add this IP address at the Access Methods area in the Control panel, the online account management system.
  2. Configure your equipment to send all telephone calls to a gateway. The gateway IP address is 213.228.232.116.  If possible, we recommend that you use the DNS named dnns.maxatel.com.

Dynamic IP address (Your ISP change your IP address regularly)

  1. Make sure that your MAXATEL Phone Account has been configured for dynamic IP addresses. If you did not do this while setting up your account, then set this option now at the Access Methods area of your Control panel, the online account management system.
  2. Configure your equipment to send all telephone calls to a gatekeeper. The gatekeeper IP address is 213.228.232.116. If possible, we recommend that you use the DNS name dnns.maxatel.com.
  3. Configure your equipment to register at the gatekeeper using an E164 alias (telephone number) or an H.323 alias. The alias address should be 1822 followed by your MAXATEL Phone Account number followed by your account password (emailed to you when you set up your account).  For example, if your account number is 200100 and your password is 900100, set the E164 alias to be 1822200100900100.

The codecs we support are G.723.1 and G.729. You should enable both Fast Start and H.245 tunneling.

We support fax calls to most worldwide destinations. To send faxes, your gateway must be T.38 compatible and use the H.323 protocol.

The codecs we support are G.723.1 and G.729.  We do not support fax using the SIP protocol.


 Audio quality
Audio quality on the Internet based MAXATEL network is equal to the quality on standard fixed telephone lines. You will enjoy the highest voice quality and the lowest delays if you use an IP phone such as the Cisco ATA 186 or the Elesign ESC1710.

If you plan to make calls through MAXATEL using our softphone on your computer, we offer the following advice:

  1. Use a headset.
  2. USB headsets often offer higher quality than sound card headsets, but are a little more expensive.
  3. Do NOT use desktop speakers for listening to the call.  Although the quality may sound fine to you, the people you call will hear a disturbing echo.

Testing
We offer a simple test facility on our servers that you are welcome to call for testing.This should work, even if you do not have a MAXATEL VoIP Phone Pccount.To call it, configure your software or hardware dialler to send calls to MAXATEL, and then dial 123. You should hear a test announcement. If you hear this, then your equipment is set up correctly and you should be able to use MAXATEL VoIP. Once you have established an account. Also, make a call to 124. If you can hear the announcement on 123, but not the announcement on 124, then you have a firewall/router related problem.


Commercial terms
Our service is prepay. The quickest and easiest way to pay us is using our 128bit SSL 3D-secured pay gateway. Although you should always allow twenty-four hours for a payment to be credited to your account, you will find that your payment is often added to your MAXATEL Phone Account within a few minutes of being sent.
