DIDHub for Zoom Phone BYOC
Bring DIDHub numbers to Zoom Phone via Zoom's BYOC (Bring Your Own Carrier) program. Numbers in 80+ countries — including markets Zoom-provided numbers don't cover.
Why DIDHub + Zoom Phone BYOC
Zoom Phone BYOC (Bring Your Own Carrier) is Zoom's pattern for connecting third-party SIP carriers to a Zoom Phone tenant. It exists for one main reason: Zoom-provided numbers don't cover every country. If you need a Zoom Phone user in Israel, India, Saudi Arabia, Brazil, or several other markets, BYOC via DIDHub is the only path.
BYOC also helps with cost: Zoom-provided numbers in supported countries can be 2-5× more expensive than DIDHub flat per-DID pricing at scale. Tenants with 50+ Zoom Phone seats often switch to BYOC purely for the savings, even in countries Zoom natively covers.
Setup — 30-60 minutes
BYOC takes 30-60 minutes — most of the time is Zoom's own provisioning, not DIDHub's side.
Sign up + buy a number
DIDHub account, pick a DID. Zoom BYOC supports US, UK, EU, IL, IN, BR, JP, AU, ZA, and 60+ more countries via DIDHub.
Open Zoom admin → Phone System Management → BYOC
If you don't see BYOC, your Zoom plan may need to be upgraded — Zoom Phone Pro or Business with BYOC entitlement.
Add a SIP trunk
Provider name = DIDHub. Paste DIDHub-provided trunk endpoint, credentials, and IP allowlist values.
Configure inbound + outbound routing
Inbound: assign DIDHub DIDs to Zoom Phone users. Outbound: set the user's outbound calling line to use the DIDHub trunk.
Provision DIDs in Zoom
Zoom imports DIDHub-provisioned DIDs as BYOC numbers. Assign one to each user that should have a phone number.
Test
Call into the DID; have a Zoom Phone user dial out. Both should route via DIDHub's edge.
SIP trunk configuration
The exact trunk values DIDHub provisions for your account. Pre-fill these in the Zoom Phone BYOC trunk-config UI:
# Zoom BYOC trunk values from DIDHub Trunk Type: SIP (TLS preferred) Server URL / FQDN: byoc.zoom.didhub.io SIP Port: 5061 (TLS) or 5060 (UDP — testing only) Authentication: SIP digest Username: byoc_xxxxxx Password: (provisioned per Zoom tenant) Allowed source IPs: Zoom's published BYOC ranges (DIDHub allowlists automatically) Codecs: G.711 ulaw/alaw, OPUS optional SRTP: Required (Zoom mandates encrypted media on BYOC)
Zoom BYOC is opinionated about media encryption — SRTP is required. DIDHub's BYOC trunks ship with TLS + SRTP enabled. Zoom publishes its source IP ranges; DIDHub allowlists them automatically when you create a BYOC trunk.

Frequently asked questions
Is Zoom Phone BYOC the same as Zoom-provided numbers?
Different. Zoom-provided numbers come from Zoom directly with bundled per-user pricing. BYOC means YOU bring the carrier (DIDHub) — flat per-DID pricing, broader country coverage, more carrier flexibility.
Which Zoom plan do I need?
Zoom Phone Pro or Business is required for BYOC. Free Zoom Phone (where available) doesn't include BYOC.
Does BYOC work with Zoom Contact Center?
Yes. Zoom Contact Center supports BYOC carriers; DIDHub plugs in identically to a Zoom Phone trunk.
Can I mix Zoom-provided and BYOC numbers in the same tenant?
Yes. Zoom supports mixed routing — some users on Zoom-provided, others on BYOC. Useful during gradual migration.
Does Zoom require any specific certification for BYOC carriers?
Zoom maintains a list of BYOC-eligible carriers; DIDHub is operated as a BYOC-eligible carrier with the standards Zoom requires (TLS+SRTP, attestation handling, NAT traversal). No additional cert needed from your side.
