We have this system setup in one of our customers:
PBX in a Flash Version = 220.127.116.11 Running on HARDWARE │
│ FreePBX Version = 18.104.22.168 │
│ Running Asterisk Version = 1.4.42 │
│ Asterisk Source Version = 1.4.42 │
│ Dahdi Source Version = 22.214.171.124+126.96.36.199 │
│ Libpri Source Version = 1.4.12 │
│ Addons Source Version = 1.4.13
We are using a Rhino R1T1 connected to a VoIP PRI from Verizon, the issue that is happening is that in the middle of the call or when they parked the call the call disconnect, checking the logs i notice that i’m getting a lot of cause 16:
Span 1: Channel 0/8 got hangup request, cause 16
as per this link:
This cause is due to unspecified cause.
Everything else since to be ok, i think that has to be something on the provider end, but i would like to be 100% sure that is in their end, We ran network lines to split the network and the phones and the issue still, also from time to time they are getting chopping/cutting any other word conversation.
I think that it may be something on Verizon end.
Any advise? thank you in advance.
