Enterprise VoIP with HD SIP trunks that cut your phone bill by up to 60%
Cloud or hybrid IP telephony with HD quality, number portability, mobile softphone and CRM integration. Replace your analog PBX with a VoIP operation managed 24/7 by BITS from Mexico — no PSTN line rental, no long-distance surprises.
$50,000 a month for a PBX nobody knows how to fix anymore.
A company with 180 extensions was paying MXN $52,000 a month between line rental, long distance and maintenance on a 2009 analog PBX. No mobility, no recording, and every failure meant a technician with minimal coverage. With BITS VoIP on 3CX plus a redundant SIP trunk they migrated without downtime, cut the bill to MXN $16,800 and rolled out a mobile softphone for the entire sales team.
The real cost of staying on PSTN
Line rental, per-minute long distance, maintenance on a discontinued PBX and zero visibility by extension or department.
The cost of migrating to VoIP badly
No SBC, no QoS, no formal portability or a single-carrier SIP trunk — voice breaks up and the bill goes up.
BITS VoIP, managed end to end
3CX, Wildix, Teams Phone or FreePBX with redundant SIP trunks, IFT portability, CRM integration and a 24/7 NOC with SLA.
