Failed to ping Broadsoft XSP Domain

[TriciaWang0860]

Dear Sir, I create a group on sandbox, and I received an email from the server. And I try to register the sip account, but fialed. The I try to ping to broadsoftlab.com, but failed as well. Do you think what should I do ? Is it a network issue or others? Thanks.

Please refer back to the DevNet reservation page and re-reserve the lab sandbox.

The broadsoftlab.com" is an internal domain and will not be pingable.

Phone devices are required to be configured to point to the Outbound Proxy.  From there, SIP messages will be proxied to the "broadsoftlab.com" domain.
