Figure 12: Edit VoIP Service Provider
The Edit Service Provider page gives you the ability to change your
caller ID, as well as select a range of codecs.
Username/Password - You will need to provide your log on creden-
tials in order to update your service provider information.
Caller ID - The caller ID sent to the PSTN will be set to the value
specified in this field.
Codecs - Codecs provide the ability for your voice to be converted to a
digital signal and transmitted across the Internet. The quality of your
call can be affected by the choice you make. The codecs available to
you will depend on what is supported by the service provider you
choose. You can select the order in which the codecs are used. The
codecs commonly available are u-law, a-law, GSM, G.726, G.722, and
G.729A. A registered G.729A license is required in order to use the
G.729A codec.
