Why Businesses Switch from Twilio
Twilio is a powerful platform for developers building custom communications applications. But if you need SIP trunking for your PBX, there's a simpler path.
API Complexity
Twilio's Elastic SIP Trunking requires using their console and API to configure trunks, set up origination/termination URIs, and manage credentials. IPComms uses standard SIP — point your PBX at our server and you're connected in minutes.
Higher Per-Minute Costs
Twilio charges $0.014/min outbound (US) vs IPComms' $0.010/min. On top of per-minute charges, Twilio also bills per API request, per recording minute, and per transcription. Those costs add up fast for high-volume callers.
Support Gap
Twilio's support assumes developer fluency — documentation, Stack Overflow, and community forums. Phone support requires an enterprise plan. IPComms provides real human support via phone and email for every customer, regardless of plan size.

Frequently Asked Questions
Common questions about switching from Twilio to IPComms.
Is IPComms cheaper than Twilio for SIP trunking?
Yes. IPComms charges $0.009/min inbound and $0.010/min outbound, compared to Twilio's $0.0085/min inbound and $0.014/min outbound. IPComms has no channel fees and no per-request API charges. For a business making 10,000 minutes of outbound calls per month, IPComms saves approximately $40/month on calling costs alone, with additional savings from zero API request fees.
Can I switch from Twilio to IPComms without downtime?
Yes. You can port your existing phone numbers from Twilio to IPComms with zero downtime. The porting process typically takes 3–10 business days depending on the releasing carrier and 5-7 days for toll-free numbers. During the transition, you can set up IPComms SIP trunks alongside Twilio and switch over when ready.
Do I need developers to use IPComms SIP trunking?
No. Unlike Twilio which requires API integration and developer expertise, IPComms uses standard SIP protocol that works with any SIP-compatible PBX (Asterisk, FreePBX, 3CX, FreeSwitch, Microsoft Teams, etc.) out of the box. Configuration takes minutes, not days of development.
Does IPComms offer the same features as Twilio Elastic SIP Trunking?
IPComms covers all core SIP trunking features: inbound/outbound calling, number porting, local and toll-free DIDs, E911, caller ID, TLS/SRTP encryption, STIR/SHAKEN, and geo-redundant infrastructure. Twilio offers additional programmability through APIs (SMS, video, programmable voice), which is valuable for developers but unnecessary for businesses that just need reliable SIP trunking for their PBX.
What PBX systems does IPComms support?
IPComms works with any standard SIP device or PBX: Asterisk, FreePBX, 3CX, FreeSwitch, FusionPBX, Issabel, Kamailio, Yeastar, Cisco CUBE, Avaya, Genesys, and Microsoft Teams via Direct Routing. Twilio's Elastic SIP Trunking also supports SIP devices, but configuration is more complex and requires using their API console for setup.
How does IPComms support compare to Twilio support?
IPComms provides real human support via phone, email, and ticket for all customers — no minimum spend required. Twilio's phone support is limited to enterprise-tier customers paying significantly more. Standard Twilio support is community forums and documentation, which assumes API development knowledge.
