Frequently asked questions
What is SIP trunking and how does it work in Croatia?+
SIP trunking replaces traditional phone lines with a secure internet connection between your PBX and the public telephone network. In Croatia, AstraQom delivers local +385 numbers and outbound voice over Tier-1 routes, in Zagreb, Split and Rijeka and nationwide.
Can I keep my existing Croatia phone numbers?+
Yes. We port your existing fixed, mobile and toll-free Croatia numbers from any licensed operator with zero downtime. Most ports complete in 2–4 weeks.
How fast can I get a +385 number?+
Most numbers activate within 1–3 business days. Toll-free and special numbers can require extra local KYC — we handle the paperwork end to end.
How reliable is the service in Croatia?+
We use geo-redundant SBCs, multiple upstream carriers and QoS-aware routing, backed by a 99.9% uptime SLA. 4G/5G failover and SD-WAN are available for sites that need guaranteed voice quality.
What equipment do I need?+
Most businesses need only an IP-PBX, a softphone app or a SIP-compatible handset. With a legacy PBX, we supply an enterprise SBC or ATA adapter so you can keep your existing phones.
Is the service compliant with Croatia telecom regulations?+
Yes. AstraQom operates under the HAKOM framework and handles KYC, numbering and emergency-calling compliance during onboarding, so you get a licensed route without the regulator paperwork.
How much does SIP trunking cost in Croatia?+
Trunks start from $9 per channel per month with per-second call billing. You only pay for active channels, and volume or multi-year commitments unlock significant discounts.
