Voicemail to email is not arriving or lands in spam.
The PBX often sends from its own domain or a no-reply address. Without SPF, DKIM and a clean reverse DNS, Microsoft or Google drops it in junk or rejects it.
Try this first
- 1Check the sender address and the IP the PBX uses for SMTP.
- 2Verify SPF on the sender domain, add the PBX IP or relay through SMTP.
- 3Enable DKIM on the PBX or through the SMTP provider that signs.
- 4Test with mail-tester or similar to see what is missing per section.
When to bring us in
Voicemails arrive, just late: check the PBX SMTP queue, often a DNS timeout or rate limit on the relay.
