# Cascades Fax Architecture — PacketDial WhiteLabel
|
|
|
|
**Captured:** 2026-04-24 by Howard
|
|
**Screenshots:** `docs/servers/fax-packetdial-whitelabel/`
|
|
|
|
## Upstream provider: PacketDial (WhiteLabel aka WL)
|
|
|
|
- **Dashboard:** https://voip.packetdial.com/
|
|
- **Account:** `28598` ("CASCADES OF TUCSON" per footer)
|
|
- **Platform:** PacketDial v5.17 hosted VoIP + eFax service (private-label reseller of VoIP infra, hence "WhiteLabel")
|
|
- **Admin contact:** `CS` login (Cascades admin account — whoever logs in from the MSP side)
|
|
|
|
## The three Cascades fax boxes
|
|
|
|
Each fax box receives inbound faxes from a PSTN number, then emails the fax as an attachment to a specified M365 address.
|
|
|
|
| Box name | Inbound DID | Caller ID | Routes inbound fax to (email) | Faxbox domain |
|
|
|---|---|---|---|---|
|
|
| **Med Tech** | (520) 347-8490 | "CASCADES" | `medtech@cascadestucson.com` | `medtech.faxboxes.com` |
|
|
| **Nurses/RCC** | (520) 347-8460 | "CASCADES" | `fax@cascadestucson.com` | `nurses.faxboxes.com` |
|
|
| **Sales** | (520) 347-8449 | "CASCADES" | `crystal.rodriguez@cascad...` (truncated in screenshot) | `ctsales.faxboxes.com` |
|
|
|
|
All three: Outbound Faxing = Enabled, Retries on fail = 1, Sent Receipts = On, Timezone = Mountain (w/o DST), Allowed Senders = `@cascadestucson.c...` (any internal user).
|
|
|
|
## Inbound flow for the `fax@` mailbox (Nurses/RCC line)
|
|
|
|
```
|
|
PSTN fax → (520) 347-8460 → PacketDial "Nurses/RCC" fax box
|
|
→ email delivery to fax@cascadestucson.com
|
|
→ Exchange Transport Rule "Fax Forward and Retain Copy" (Priority 0, Enabled)
|
|
→ BCC to 9 recipients (as of 2026-04-24):
|
|
- anna.pitzlin@ [BROKEN — account deleted 2026-04-22, NDRs on every fax]
|
|
- christina.dupras@
|
|
- veronica.feller@
|
|
- medtech@
|
|
- karen.rossini@
|
|
- lois.lane@
|
|
- christine.nyanzunda@
|
|
- ashley.jensen@
|
|
- Britney.Thompson@ [will break post-Litigation Hold + disable]
|
|
```
|
|
|
|
## Known issues (2026-04-24)
|
|
|
|
| Issue | Impact | Action |
|
|
|---|---|---|
|
|
| Anna Pitzlin in BCC list but mailbox deleted 2026-04-22 | Every fax generates silent NDR for Anna | Remove from rule immediately |
|
|
| Britney Thompson in BCC list, scheduled for disable post-Litigation Hold | Will break future faxes once she's disabled | Remove before disabling her |
|
|
| Ashley Jensen reports lost access to `fax@` mailbox | She is in BCC list so receives copies, but may have lost direct delegate/FullAccess on the `fax@` shared mailbox — separate from BCC | Grant Ashley FullAccess on `fax@` shared mailbox directly |
|
|
| Transport rule model is brittle — every staff change requires rule edit | Operational debt | Refactor: grant FullAccess on `fax@` shared mailbox to all 9 BCC recipients, delete the transport rule entirely, users open `fax@` as secondary mailbox in Outlook |
|
|
| Sales fax → crystal.rodriguez@ (single person, no redundancy) | If Crystal leaves or is OOO, faxes go unseen | Consider a shared mailbox for sales faxes too |
|
|
| Med Tech fax → medtech@ role mailbox | Current role-mailbox model is under G2 conversion review per master plan | When G2 converts medtech@ to shared, the fax routing continues to work (emails still land in the mailbox) |
|
|
|
|
## Outbound faxing
|
|
|
|
- Allowed senders: anyone with an `@cascadestucson.com` address can send via the PacketDial relay
|
|
- Outbound path not documented in screenshots — presumably SMTP relay from Exchange Online to PacketDial's ingress with Allowed Senders enforcement
|
|
|
|
## Access to PacketDial admin
|
|
|
|
Login path not yet vaulted. TODO: add PacketDial admin creds to vault at `clients/cascades-tucson/packetdial-whitelabel.sops.yaml` next time we need to change a fax box config.
