Blue Chip SIP for WhatsApp bridges voice calls from the WhatsApp and WhatsApp Business apps on a mobile device into your IP PBX — SIP trunk style. Keep the number customers already know, run inbound through desk phones, softphones, and queues, and place outbound calls WhatsApp-first with automatic landline fallback when needed.
Request a quoteCustomers already call businesses on WhatsApp. The problem is treating that number like a single mobile phone instead of a shared business line.
Once WhatsApp calling is presented as a SIP trunk, you can apply the same business voice controls you already trust for ordinary phone calls.
Ring WhatsApp calls to extensions on desk sets and softphones so the right person can answer without holding the mobile handset.
Keep one WhatsApp number customers already save, while several team members handle inbound volume together.
Send busy periods into call queues so callers wait in line instead of bouncing off a single busy mobile.
Route WhatsApp voice calls to an AI receptionist — or send them to a ring group / call queue or a direct extension — without a DTMF IVR menu.
Blind or attended transfer between agents, with presence so calls go to people who are actually available.
Apply call recording, CDR, and reporting policies already configured on your PBX for quality and compliance needs.
Open/closed schedules, after-hours announcements, and night service — without leaving a mobile on a desk overnight.
Unlike typical WhatsApp / WhatsApp Business mobile apps that handle one call at a time on a number, the SIP bridge supports concurrent calls on the same WhatsApp number — sized in blocks of 2 simultaneous calls per number.
Place outbound calls from your PBX with WhatsApp first. Built-in auto-sensing checks whether the destination is on WhatsApp; if it is not, the call is rejected, or the person is busy, the gateway signals your PBX to use the secondary landline route on your outbound rules.
Designed for SIP-based systems such as 3CX, Asterisk/FreePBX, PortSIP, and similar IP PBX platforms.
A practical setup path for businesses that already use WhatsApp or WhatsApp Business on a mobile device and already run an IP PBX.
Blue Chip sets up the SIP trunk path sized for the WhatsApp numbers and simultaneous calls your team needs.
Connect the mobile app customers already use — typically with a QR code link — so voice calls can be bridged without asking customers to change habits.
Present WhatsApp calling to your PBX as a SIP trunk so you can route to a ring group or call queue, a direct extension, or an AI receptionist.
Point PBX outbound rules at the SIP for WhatsApp trunk first. Auto-sensing detects whether the number is on WhatsApp and places the call there when it is. If the number is not on WhatsApp, the call is rejected, or the person is busy, the gateway tells your PBX to continue on the secondary landline route.
Send inbound calls to a ring group or call queue, a direct extension, or an AI receptionist — with business-hours rules and transfers between agents.
Inbound is only half the story. Your agents can dial from the PBX and prefer WhatsApp when the destination supports it — without changing how they place a call.
Configure the PBX so outbound calls try the SIP for WhatsApp path first. When someone is reachable on WhatsApp, the solution detects that and places the call there automatically.
Built-in auto-sensing checks whether a number is on WhatsApp. If it is not, or the person rejects the call or is busy, the gateway sends a signal back to your PBX so the call can continue on the secondary landline route configured in your outbound rules.
