If it does not work

• Registration rejected (403) : login, password, From domain.
• No response to registration : host, port, firewall, SIP ALG.
• Inbound rejected: No matching endpoint found : provider IPs missing from identify.
• Extension not found in context : the inbound number arrives in another format.
• No joint codecs (488) : allow the provider codecs.

Check whether the provider server answers: SIP check. Read a registration or call log: SIP log analyzer. No audio: NAT test.
