Hi Group,

We have an issue here where we are not able to make inbound/outbound calls using a websocket application that uses sipjs.
We think that wan.auto is not excluding IPv6. This problem is related to ICE. There was a bug on this that was fixed in 1.4.19.

Additional info:

- FS version: 1.4.23 (also tried upgrading to 1.4.26)
- IPv6 is disabled in the OS

We have the below in logs:
[WARNING] switch_core_media.c:2790 NO candidate ACL defined, Defaulting to wan.auto

It would be great to have ideas on what could be the reason.

Thanks,
