- 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.
