update 18v3 sip problem

[mcnick50]

hello,

i have many installations in Greece with OTE sip trunk. with 18 v2 everything works fine. when i update to 18v3 the sip shows registered but i get 404 when i try to call and no incoming calls. when i click refresh registration starts to work for a while and again the same problem. all installations are local with windows server 2022.

Hi

Unless OTE is a supported provider, your best be is to start troubleshooting with OTE support. Video below for v16 but the concepts are the same.

server 2022

Note Server 2022 isn't supported either.

Under Settings -> Advanced- Network is it set to dynamic ? If so set it static - 3cx are going to release a fix to resolve this issue

Other SIP providers seems to be affected in U3 , seen posts about OVH too, what Saqqara posted above is a 3CX Staff workaround, so it should save you until a fix is available.

i have dynamic ip

They mean, set it to static anyway, to resolve the bug. Hopefully they'll have a fix before your IP changes again.

As mentioned setting your IP to static should resolve your issue until the fix comes out. If your IP changes frequently and you can't wait then contact me through a p.m. and we will see how we can assist you sooner.
