I am going to be very upfront, I have absolutely NO KNOWLEDGE of VoIP systems. I am learning because I just inherited a Asterisk based phone system at work-it’s a very… “homebrew” type thing, managed by about 7 different individuals. I wasn’t really formally trained on the system.
So, I recently got our internet speed upgraded and have had problems with the phone system ever since. Our usable IP, gateway, dns, etc did change.
Our system contains:
25 phones (mostly Cisco SPA303’s and several Polycom’s)
3 SIP/Trunks (1 for international calling and 2 numbers from the same provider)
Linus server with Elastix running
outbound calls and internal extension calls work fine
after restarting the system via the Asterisk CLI via FreePBX (2.9), inbound calls will work for approximately 25 minutes, then the calls will go to a voicemail(? nobody is even sure how this is possible).
Elastix logs (pictured) are showing a HUGE amount of congestion(?) that aren’t even ‘real’ numbers, lasting seconds and showing as answered.
I have contacted our SIP/Trunk providers and they are saying the problem is on my end. It is imperative that I get this system back up and running.
After speaking with others that have some sort of experience with the phone system, their suggestion is to upgrade the system-it’s very, very old and has been restored 100 times via very old backups. Where would I even start with this endeavor?
After poking around, I realized all the inbound “congestion” is a number that is 4 digits + the static IP
This 4 digits go up by one digit each time.
Can somebody PLEASE help?
