Many CRM calling systems bring telephony into the CRM. Tabd takes a different approach: connect your existing SIP accounts and PBX to a browser phone, so your team can modernize calling without replacing the telephone system behind it.
Designed for compatible SIP and PBX setups · No new phone numbers required
Keep your provider, numbers, SIP extensions, and PBX routing in place. Tabd sits on top as the browser interface for your users and team.
Retain the routing, extensions, queues, and call rules your business already operates.
Add calling, call history, recordings, enabled transcriptions, and team visibility in Chrome.
Use the phone alongside CRM, helpdesk, recruiting, and other web applications.
Native CRM calling prioritizes an experience inside one CRM. Tabd prioritizes preserving an existing SIP and PBX environment while making it available in Chrome.
| Question | CRM calling system | Tabd |
|---|---|---|
| Must we replace our existing provider? | Sometimes, depending on the CRM and calling setup | No |
| Can we keep existing SIP extensions? | Often limited or provider-dependent | Yes, with a compatible SIP setup |
| Can we keep existing PBX routing? | Often limited or integration-dependent | Yes |
| Must we purchase new numbers? | Sometimes | No |
| Can agents call from the browser? | Yes | Yes |
| Can it work outside one specific CRM? | Usually tied to that CRM | Yes, through the Chrome extension |
| Can it support workflows across multiple CRMs? | Not normally | Potentially, as integrations become available |
| Are calls logged inside the CRM? | Yes, for supported native workflows | After a supported integration is configured |
The practical decision is whether you want to adopt a new telephony stack or improve access to the one you already operate.
Your CRM can sensibly become the center of both customer data and telephony.
Your phone system already works and the browser experience is what needs to improve.
Validate fit with a compatible SIP account and a small group of users first.
Start with a compatible account from the phone environment you already manage.
Check inbound and outbound calling, audio behavior, history, and your team’s browser workflow.
Assign compatible SIP extensions while retaining the provider, numbers, and PBX logic underneath.
No. Tabd adds a browser calling interface to a compatible existing SIP and PBX setup. Your PBX remains responsible for the telephony rules and routing you already use.
No. Tabd is designed to work with the SIP extensions and phone numbers already connected to your existing telephone system.
No. CRM logging depends on a supported integration and its configuration. Without one, calls and related activity remain available in Tabd rather than being automatically written to the CRM.
Not at all. It can be the simplest option for a company starting without an existing phone system. The key question is whether you want a new telephony stack or a browser layer for the one you already operate.
See whether browser calling fits your team before considering a broader provider, number, or PBX migration.
