Exercise 1 – Configuring Phone Extensions on the Elastix Server

Task 1: Take a screenshot of the Add an Extension page showing that extension Softphone 1 <101> was created on ELASTIX_SRV as demonstrated in Figure 10.

Task 2: Take a screenshot of the extension 101 configuration page as demonstrated in Figure 8. It should show the configuration parameters of newly created extension.

Task 3: Take a screenshot of the Add an Extension page showing extension Softphone 2 <102> was created on ELASTIX_SRV as demonstarted in Figure 12.

Task 4: Take a screenshot of the extension 102 configuration page as demonstrated in Figure 11. It should show the configuration parameters of newly created extension.

Exercise 2 – Configuring X-lite Softphones

Task 5: Take a screenshot of the softphone panel showing its name (i.e., Softphone 1) and status (i.e., Available) as demonstrated in Figure 15.

Task 6: Take a screenshot of the softphone panel showing its name (i.e., Softphone 2) and status (i.e., Available) as demonstrated in Figure 17 above.

Exercise 3 – Testing Calls Between X-lite Softphones

Task 7: Take two screenshots of Softphone 1 calling Softphone 2 and Softphone 2 calling Softphone 1, respectively, as shown in Figures 18 and 19.

Exercise 4 – Exploring Codecs Available to the X-Lite Softphone

Task 8: Question: Provide a one-paragraph description for each audio and video codec on your list. Use the textbook and Internet as needed. Cite references used in this research.

iLBC (internet Low Bitrate Codec) is a FREE speech codec suitable for robust voice communication over IP. The codec is designed for narrow band speech and results in a payload bit rate of 13.33 kbit/s with an encoding frame length of 30 ms and 15.20 kbps with an encoding length of 20 ms.

Speex works for narrowband...
