Dear Colleagues,
I need a guidance regarding remote registration / registration proxy on Expressway Edge to Core.
Currently the remote registration has been enabled by the followings:
- Traversal zone between Core and Edge
- Search rule on Edge
Protocol: SIP (All variants)
Source: Default zone
Mode: Any alias
Target: Traversal zone
By these settings, all external requests are forwarded to the Core, including inappropriate calls.
I was thinking that is there any way to filter/enable the registration requests (like in MRA) and the targeted calls only?
When I modified the search rule above to use .*@domain.com.* regex pattern, all external registrations were dropped.
Unfortunately the MRA scenario can be used for UCM registration only, as far as I know.
Thanks,
Laszlo
