We’ve been advised that the validation process has resumed following the end of the National Day holiday period. Our partners are working closely with the local telecom provider to lift the outbound call restrictions as soon as possible. We will provide further updates as more information becomes available.

We have received confirmation that governmental departments have temporarily suspended all changes to the PSTN due to the upcoming National Day holiday. As a result, outbound calls are expected to remain masked until approximately mid-October.

We are doing everything possible to restore normal service sooner; however, the timeline is dependent on Chinese government processes.

Please note that inbound services continue to operate as normal.

The regulatory assessment is nearly complete, and we are now working with our downstream partner to remove the temporary workaround and restore normal service.

Full inbound functionality has been reinstated, and work is underway to restore outbound calling and CLI passthrough. In the meantime, outbound calls continue to route with a temporary CLI.

If you require further information, please contact us at servicedesk@loopup.com. We will provide further updates as more information becomes available.

The risk assessment is still ongoing. We’ve been advised that the regulator is working to complete the required checks as quickly as possible.

Unfortunately, some services remain affected. Outbound calls are still being masked as a temporary workaround.

We will continue to share updates as soon as more information becomes available.

We’ve been informed that the ongoing maintenance may also affect other cities. Outbound calls are still being masked and should route correctly while the assessment is carried out.

We expect to receive an official document from the regulator next week outlining the full impact and estimated restoration times. Further updates will be provided as soon as this information becomes available.
