Hi Richard,

It been repeated hundreds of times and it is the subject of the topmost topic on this forum:

set verbose log level and then restart PBX...
To be sure that the SIP traffic sent by provider reaches PBX host, you can use WireShark. It will show you all incoming packets comin to PBX host. If there are no SIP requests received from VoIP provider then problem can be described in PBX log.
