Here are some guidelines to follow to ensure great VoIP call quality!
Calculate required bandwidth (see bandcalc.com). Rule of thumb is that in each direction for each line you need 32kbps for G.729a and 80kbps for G.711u. Both codecs are supported by Cloudli across the network.
Pay attention to upload speed. Most ISPs provide lower upload than download speeds.
Also pay attention to the monthly Internet usage of the DSL/Cable plan.
If you use a lot of bandwidth for video, file archiving or other applications, having a dedicated Internet link for VoIP or implementing Quality of Service (QoS) on your single data link will greatly decrease the probability of voice quality problems
Having a robust Internet connection from your premise to Cloudli will also decrease the probability of voice quality problems. Ask your technician to test the path of IP traffic to Cloudli to ensure minimal packet loss and delay.
