Registration proxy on Expressway Edge

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

Hi,

You should try the suffix option with the appropriate domain, instead of regex pattern.

Regards,
