Lately we are encountering a weird issue where a voice gateway randomly doesn't work properly : either is an incoming or outgoing call, both ends can't hear each other during the first 10 seconds, and everything goes back to normal after, the only thing that helps to fix it temporarily is issuing a "reload" to reboot it and it works just fine
- I tried to look at the CPU usage when the issue is happening and it looks clearly it isn't the source of the problem
- issuing "Debug isdn Q931" during the problem shows that the call is instantly taken by the phone.
If you can suggest any other troubleshooting tips for such issue please advise
Ah, wanted to add that and forgot
It's a BRI (4 ports).. if you need other information than this, I will do this once in the office
The same config is deployed in multiple remote sites without any issue, also, when rebooting the router it works fine for 4, to 5 days .. so i don't think it's a configuration issue
I dont think its a problem with the dial-peer. I never worked with BRI , but Can you share the show controller bri output.
Fine, is there any time negotiation happening between the BRI configured router and the ITSP? if so then we need to check any mismatch happening during the negotiation. because ISP to ISP time may differs.
