While still under the SIP menu select SIP Extensions and perform the following
| Field | Setting |
|
| Support PRACK method with provisional response reliability: | UNCHECKED |
|
| Encode SIP URI with user parameter: | UNCHECKED |
|
| INVITE Expires Timer Value (sec): | 3600 |

|
| Send RTP on 183 Session Progress: | CHECKED |
|
Once done click on the Save SIP Extension Settings button on the bottom of the page to save your changes.
|
| STEP 3 |
Configure extra settings (Line1) |
|
Now we will configure the necessary settings such as your DTMF settings.
Click on Line1 and perform the following
| Field | Setting |
|
| Send Out-Of-Band Telephone Events: | RFC 2833 |

|
Once done click on the Save SIP Extension Settings button on the bottom of the page to save your changes
|
| STEP 4 |
Configure codecs |
|
We are almost done and just need to make sure that our codecs have been configured properly. Since the AC-211 only supports one compressed/complex
codec at a time you will have to make a choice between G723 and G729 as your compressed codec. We recomend using G729 however some users may find
that G723 sometimes provides better audio clarity. In the end it depends entirely on user preference and you may choose to use whichever codec works
best for you.
Select CODECS from the menu on the left side of the page and set the following
- Enable a complex codec, either G729 or G723
- Set Packetization for each codec to 20ms.
Note that you will not be able to set the packetization time for the G723 codec.
- Set Silence Surpression to OFF for all codecs.
- Select either G729 or G723 as your preferred CODEC option.
*Optionally if you will be using fax please set the FAX Preferred CODEC to G711U.
- Leave your Jitter Bufer set to Adaptive Jitter Buffer: at 100ms.
Once done click on the Save CODEC Configuration button on the bottom of the page to save your changes
|
| STEP 5 |
Check status |
|
You will now want to check to make sure that your AC-211 is registered.
To do that click on the SIP option from the
menu on the left side of the page then click on Line1.
You should see Registered as your Registration state.
If you do not see this please double check your configuration and then reboot your AC2-11 by turning it off for 30 seconds and turning it back on.
If you do see that your "Registration state" says "Registered" then That's it! You can now make a phone call.
|
| STEP 6 |
Placing Test Calls |
|
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you
can place a call to a traditional landline or mobile phone by dialing either:
1 + the area code and number for calls to the US
Or
011 + the country code, area code, and number for calls worldwide
(you may also use 00 instead of 011).
To test inbound calls from Callcentric to your Asterisk installation, follow the directions
listed in this FAQ. |
