Just to close the loop, my IP address never changed again. I have a static IP from ISP now and all working. A little frustrating, but the static IP was not expensive as it used to be.
I have the same problem with a few of my systems connected via ISPs with dynamic IP adresses.
To fix the issue, I was think about using a fake IP address instead of a DDNS name (in SIP and ChanSIP settings). Since there is no external phones, I donât think that it would affect the system.
Would this be a good workaround ?
I know itâs dumb, but some customers donât want to pay for a fixed IP.
Without an external address, you wonât be able to call into the system. If thatâs not a problem, youâre golden.
Isnât that only an issue if you have external extensions ?
I thought that these âpublic IPâ settings were only useful for external extensions.
I did the test and it seems to be working fine. I have a SIP trunk connected to VOIP.ms and the system can receive calls even with the fake IP. I tried to disable and re-enable the trunk and it still works.
I guess youâre good.
