I'm having voice quality issues. During a conversation, a call gets more and more faint going into a metalic sound to the point where you just hang up.
This happens on calls to the PSTN and accross the WAN. The router has a PVDM2-48. How do you calculate how many calls can be made with this PVDM? How do I know if I'm going over the alloted resources?
I did a test and got this. Does it mean I missing something?
