Troubleshooting

Why can't I receive calls from outside Callcentric when using a Callcentric number as the callerID?
Calls are not routed solely based on caller ID; however the caller ID is taken in to account for some routing and billing purposes. Because of this, on an incoming call from outside the Callcentric network, if you pass a caller ID of a Callcentric DID/number the call will not be processed properly and will fail. We do this to prevent callerID spoofing.

You will generally hear the call ring endlessly or simply fail to fast busy signal. We will not accept these calls and they will not show up in your calling reports. In order to avoid this please do not use a Callcentric DID as the calleriD of an incoming call into the Callcentric network.

NOTE: The above also applies to SIP URI calling.
