Setting Up a SIP Trunk in Israel: a 2026 Guide for Growing Businesses
Everything Israeli businesses need to know about SIP trunking in 2026 — local DIDs, MoC compliance, redundancy, and how to migrate off legacy PRI lines.
Why Israeli businesses are leaving PRI behind
Legacy E1/PRI lines from incumbent carriers are expensive, inflexible and slow to scale. A SIP trunk replaces them with channels delivered over your existing internet, scales instantly, and gives you a single bill across all of your offices in Tel Aviv, Jerusalem, Haifa and beyond.
What is a SIP trunk?
A SIP trunk is a virtual phone line that connects your on-premises PBX (or cloud PBX) to the PSTN over IP. Each trunk supports a configurable number of concurrent channels — pay for capacity, not for physical wires.
What you get with an Israeli SIP trunk
- Local +972 DIDs in any city — present a Tel Aviv (3), Jerusalem (2), Haifa (4) or mobile (5x) number to your callers
- Unlimited inbound minutes on most plans
- Per-second outbound billing to Israel and 200+ destinations
- Encryption (SRTP + TLS) for sensitive industries — finance, healthcare, legal
- Carrier redundancy — calls failover across multiple upstream Israeli carriers; no single point of failure
Compliance: Ministry of Communications
The Israeli Ministry of Communications (MoC, משרד התקשורת) licenses carriers and supervises number allocation. Working with a licensed partner matters: it means your numbers are properly registered, lawful intercept is handled by the carrier (not your PBX), and number portability is guaranteed.
Migration in 4 steps
- Inventory — list your existing DIDs, channels and PBX make/model
- Order trunk + DIDs — we provision in parallel with your existing service
- Test in cut-over window — point a small group of users at the new trunk
- Port numbers — schedule porting; typical downtime is < 30 minutes
Pricing snapshot
A 10-channel SIP trunk with 10 Tel Aviv DIDs and 1,000 outbound minutes per month starts well below the cost of a comparable PRI. See the live Israel SIP trunk plans for exact figures in ILS and USD.
FAQ
Can I keep my existing IP-PBX (3CX, Asterisk, FreePBX, Yeastar)? Yes — any standards-compliant SIP PBX works. We provide a tested config for the major platforms.
Do you support fax (T.38)? Yes, on dedicated fax-grade trunks. Note that ATA-based G.711 fax is discouraged on internet links.
What about CLI presentation rules? Israeli regulation requires the calling number to be a number you legitimately own. We enforce this at the trunk level to keep your traffic compliant.
