OVERVIEW
SIP Trunks & VoIP Internet Connectivity for Karnataka Businesses
Voice quality on VoIP depends entirely on the quality of your internet connection. Jitter, packet loss, and latency from consumer broadband cause call drops, echo, and poor audio. BTNL’s leased line provides dedicated, low-jitter internet with VoIP traffic prioritised via QoS — ensuring every call is clear, every time. Fully compatible with all major IPPBX and SIP trunk providers.
WHAT’S INCLUDED
Complete Service Features
Dedicated VoIP Bandwidth
Reserved bandwidth channel for voice traffic — separate from data usage. VoIP never competes with file downloads or video meetings.
QoS Voice Prioritisation
Traffic shaping that always gives voice packets the lowest latency and highest priority. No jitter, no echo, no drops.
Static IP for SIP Registration
Fixed IP address required for SIP trunk registration with providers like Airtel, Vodafone, Tata, or international carriers.
IPPBX Compatibility
Compatible with Asterisk, FreePBX, 3CX, Cisco UCM, Avaya, and all major IPPBX platforms. BTNL assists with WAN configuration.
Low Latency Connectivity
BTNL’s dedicated leased line provides sub-10ms latency for voice packets — critical for call quality, especially for contact centres.
Concurrent Call Capacity
We calculate your required bandwidth based on concurrent SIP channels (1 call = approx. 100 Kbps with G.711). Sized for your peak call volume.
Contact Centre Ready
For contact centres with 50–500 agents, BTNL provides high-capacity leased lines with QoS specifically tuned for SIP/RTP traffic.
SIP ALG Disabled
BTNL configures routers with SIP ALG disabled — a common cause of VoIP call drops that most consumer ISPs fail to address.

FAQ
Frequently Asked Questions
Why does my VoIP quality drop on broadband but not on leased line?
Broadband has variable latency and jitter — especially during peak hours. Leased line provides consistent, low-latency connectivity with dedicated bandwidth, which is what voice traffic needs.
How much bandwidth do I need for 20 concurrent VoIP calls?
Using G.711 codec, each call uses approximately 90–100 Kbps. For 20 concurrent calls, you need about 2 Mbps dedicated for voice, plus overhead. A 10–25 Mbps leased line handles this comfortably.
Does BTNL support SIP trunk connectivity for IPPBX systems?
Yes. BTNL’s static IP and QoS-configured leased line is fully compatible with SIP trunks from all major providers and IPPBX platforms including 3CX, FreePBX, and Asterisk.
Can BTNL support a contact centre with 100+ agents on VoIP?
Yes. BTNL provides high-capacity leased lines for contact centres with QoS tuned for SIP/RTP traffic, ensuring crystal-clear voice for all agents simultaneously.
