Amsterdam SIP Carrier Density
AMS-IX is the densest SIP wholesale hub in Europe. For an Issabel install with PJSIP trunks, switching carriers is config-only. The peering side stays static while you negotiate better per-minute pricing.
This makes Amsterdam the right home for Issabel builds where the SIP carrier strategy might evolve.
Build and Sizing
Issabel 4 on Rocky Linux 9, PJSIP-only, NVMe storage, 1Gbps. fail2ban with Asterisk filter, allowlist for trunk peers, dialplan CPS cap. For 100 extensions plan 4 vCPU, 8GB RAM, 200GB NVMe.
NL legal framework: GDPR, Telecommunicatiewet (licensed-operator regulation), AbuseHUB takedown process. Self-hosted PBX for a single organisation is below licensing threshold.
Codec Defaults
Default codec preference Opus, G.722, G.711alaw, G.711ulaw. Modern softphones negotiate Opus widely. PSTN trunks typically G.711alaw in EU.
For G.711 with no transcoding, 30-40 calls per vCPU. For Opus to G.711 bridging, 12-18 per vCPU.
Recording and CDR
Call recording requires GDPR lawful basis. CDR retention is your operational decision. We do not access or proxy your recordings. The Issabel backup module produces self-contained archives that restore cleanly to a fresh install.
Migration and DR
Issabel from Elastix 4 migrates via database export. Off-site replication to Romania or Finland available as add-on. Failover is manual (DNS plus config restore).
