3CX Not Responding to SIP OPTIONS messages

[dkeethler]

We are using a SIP trunk that sends in SIP OPTIONS messages to verify the trunk remains registered. However, every so often, maybe 2-4 weeks, the trunk goes unregistered and the reasoning is that the SIP Provider is not getting 200 OKs from the server. We have to manually log into the management console and re-register the trunk to fix this. Anyone else have this issue?

And yes, I know there is no support from 3CX for unsupported SIP Trunks/Providers.

Hi,

Can you ask your provider to disable this?

They cannot disable this.

Are you able to narrow down exactly when this is happening, is it happening at the same time of day or night? For something that happens every 2-4 weeks, it may very well be something to do with maintenance being carried out by your ISP, or another device on your network. Trying to track down something occurring that infrequently may prove to be be difficult.
