Features
Everything included, on every account
NextIP has no feature tiers. Whether you run one desk phone or twenty thousand channels, you get the full platform — numbers, trunking, PBX, messaging, fax and the API. You pay for numbers and minutes, not for permission to use a feature.
01
Phone Numbers (DIDs)
Local, toll-free and international numbers in 60+ countries, provisioned in seconds and portable in and out.
Local DIDs — US & Canada
Pick any available number in more than 4,000 rate centers across the US and Canada. Instant activation, no contract.
Toll-free numbers
800, 833, 844, 855, 866, 877 and 888 prefixes with per-minute or flat-rate billing.
International DIDs
Geographic, national and mobile numbers across 60+ countries for a local presence anywhere you do business.
Number porting (LNP)
Bring existing numbers over with no downtime. Port-in is free; we manage the LOA and carrier coordination.
CNAM caller ID
Outbound CNAM registration and inbound caller-name lookup so your business name shows on every call.
E911 service
Register a dispatchable address per DID and route emergency calls to the correct PSAP.
02
Calling & Termination
Carrier-grade inbound and outbound over SIP or IAX2, with route choice on every single call.
Premium & Value routes
Choose Premium for tier-1 CLI quality or Value for the lowest cost, per destination or per sub-account.
SIP & IAX2 trunking
Register any softphone, IP phone, ATA, FreePBX, 3CX or Asterisk system. Unlimited concurrent channels.
Global POP network
Register against the POP nearest your users across North America, Europe and Australia for lowest latency.
Failover routing
Automatically reroute to a second SIP URI, DID or PSTN number if your primary endpoint stops responding.
Call recording
On-demand or always-on recording per sub-account, retrievable through the portal or the API.
HD codecs
OPUS, G.722, G.711 u-law/a-law and G.729 with per-endpoint codec negotiation.
03
Cloud PBX
A full hosted phone system included with every account — no separate PBX licence, no server to run.
IVR / auto-attendant
Multi-level menus with custom greetings, DTMF routing and timeout handling.
Ring groups & queues
Sequential, simultaneous and round-robin distribution with hold music, position announcements and overflow.
Time conditions & holidays
Route by business hours, day of week and holiday calendars with an after-hours destination.
Voicemail & transcription
Per-extension boxes with voicemail-to-email attachments and optional speech-to-text transcription.
Call forwarding & DISA
Forward to any PSTN or SIP destination, or dial out through your own trunk from an outside line.
Conference bridges
PIN-protected rooms with moderator controls and per-participant mute.
04
SMS & MMS
Two-way texting on any SMS-capable DID, from the portal, the NextIP app or your own code.
Two-way SMS
Send and receive text on local and toll-free numbers throughout the US and Canada.
MMS with media
Picture and video messaging up to 1 MB per attachment on supported numbers.
Webhooks & callbacks
Push every inbound message to your endpoint as JSON, or forward it to email or another mobile number.
10DLC registration
Brand and campaign registration handled for you so A2P traffic delivers reliably.
05
Virtual Fax
Send and receive fax without a fax machine or a dedicated line.
Fax-to-email
Inbound faxes arrive as PDF attachments at any number of recipients.
Email-to-fax
Send a fax by emailing a PDF to your dedicated NextIP fax address.
T.38 passthrough
Native T.38 for existing ATAs and multifunction devices.
06
Platform & Security
The controls you need to run this as a business, not a hobby.
REST API
Every portal action is available programmatically — order numbers, manage sub-accounts, pull CDRs, send SMS.
Sub-accounts
Unlimited SIP endpoints per account, each with its own credentials, caller ID, extension and spend limits.
Fraud protection
International dialling locked by default, per-account spend caps and anomaly alerts on unusual traffic.
IP authentication
Authenticate trunks by static IP instead of a password, with per-IP ACLs.
Live CDRs & analytics
Searchable call records with cost, disposition and duration, exportable to CSV at any time.
Encrypted signalling
TLS for SIP and SRTP for media on every POP, including the browser and mobile softphones.
Compatible with the hardware you already own
NextIP is standards-based SIP. If a device or platform speaks SIP or IAX2, it works — no proprietary firmware, no vendor lock, no per-seat licence.
