SIP trunking / Talkdesk
Bring your own carrier to Talkdesk
Talkdesk xConnect BYOC terminates on your session border controller; IPComms delivers the minutes and numbers to that SBC over TLS and SRTP. $0.010 per minute outbound, $0.009 inbound, $0 per channel, no term contract.

Worked at volume
| Usage | IPComms cost |
|---|---|
| 100,000 outbound minutes | $1,000 |
| 100,000 inbound minutes, local numbers | $900 |
| 100,000 inbound minutes, toll-free | $1,850 |
| 300 concurrent calls, any month | $0 |
| 500 local numbers | $750 / month |
No per-agent and no per-channel fee on the trunk, so the comparison is minutes and numbers only. Above roughly two million minutes a month, ask for a volume rate in the form.
What you keep, what moves
Stays in Talkdesk
- Studio flows, routing, queues and the agent workspace
- Talkdesk CX Cloud reporting, QM and WFM
- Call recording inside Talkdesk
- Your Talkdesk account, region and licences
Moves to IPComms
- Minutes: inbound and outbound rated per minute, no per-channel fee
- Numbers: local and toll-free DIDs, porting at $5 per number
- E911 with a dispatchable location per number
- The carrier relationship, invoice and trunk support
How it connects
Under xConnect, your SBC sits between Talkdesk and the carrier: Talkdesk connects to the SBC over TLS only (its regional SBC endpoints answer on 5061), and the SBC connects to IPComms. Both legs run over TLS with SRTP, and so do our legs to the upstream carriers.
Trunk settings
Our side of your SBC. The Talkdesk side is TLS 1.2/1.3 only, SRTP, G.711, with an SBC certificate from a public CA, to your region’s endpoint of the form sbc2.[region].cpaas.talkdeskapp.com:5061.
- Trunk toward your SBC
- IP-authenticated SIP trunk to your SBC public address; digest registration also supported
- Protocol / transport
- SIP over TLS on 5061 with SRTP (recommended); UDP/TCP 5060 with RTP on request
- Certificates
- Our certificate chains to ISRG Root X1; trust the root, not an intermediate
- Media
- SRTP (SDES) with TLS; RTP otherwise
- Codecs
- G.711 µ-law, G.711 A-law
- Number format
- +1E.164, 1NPANXXXXXX or 10-digit for called and calling numbers, set per trunk
- Health
- SIP OPTIONS answered at both points of presence
Specifications
- Points of presence
- Two, geographically separate (US East, US West). Your SBC can be allow-listed at both; inbound calls are delivered to both.
- Upstream
- Multiple carriers, reached over SIP TLS with SRTP media; automatic failover on the outbound path
- Concurrent calls
- No per-channel fee and no set channel count. New accounts start with a fraud-protection limit that support raises on request; tell us your peak in the form.
- Caller ID
- Any number on your account, per trunk or per call; CNAM on inbound optional
- STIR/SHAKEN
- Every call is signed at A attestation, outbound and inbound
- E911
- Dispatchable location per number (Kari’s Law, RAY BAUM’S Act)
Setup steps
- Tell us your SBC and peak calls. Use the form below. We provision an IP-authenticated trunk to your SBC’s public address, send the trunk hosts for both points of presence and confirm TLS/SRTP.
- Configure the carrier leg on your SBC. Proxy set toward the IPComms trunk hosts on 5061 TLS, SRTP, G.711. AudioCodes Mediant and Ribbon notes are on our Teams Direct Routing page; Cisco CUBE has its own guide.
- Set up xConnect with Talkdesk. Your Talkdesk representative provides the regional SBC FQDN and validates your SBC certificate. Configure that trunk on the SBC with TLS 1.2 or 1.3 and SRTP.
- Numbers. Existing numbers port to IPComms in parallel at $5 each; new local and toll-free numbers are provisioned in the portal. Assign the numbers to Studio flows in Talkdesk.
- Test both directions. Inbound to a number and outbound from an agent, with Talkdesk and IPComms both watching the trunk.
Questions operations teams ask
- Is BYOC worth it at our size?
- Minutes × our per-minute rate plus $1.50 per number, against the telephony line on your current invoice. There is no per-agent and no per-channel fee on our side. A 300-seat centre doing 1.5 million minutes a month pays $15,000 in outbound usage here; put your own figure beside it.
- Do we need an SBC?
- Yes, for Talkdesk xConnect BYOC: Talkdesk connects to your SBC, and only over TLS. Talkdesk Express is different: it needs a multi-tenant trunk between the carrier and Talkdesk, which we quote case by case.
- Which SBCs?
- Any SBC that can present a public-CA certificate and run TLS with SRTP toward Talkdesk and toward us: AudioCodes Mediant, Ribbon, Oracle/Acme Packet, Cisco CUBE.
- Is the audio encrypted?
- Yes on every leg: Talkdesk to SBC (TLS, SRTP), SBC to IPComms (TLS, SRTP), IPComms to the upstream carriers (SIP TLS, SRTP).
- Do you sign calls under STIR/SHAKEN?
- Yes. Every call on the trunk is signed at A attestation, outbound and inbound. Reputation with the carrier analytics engines still depends on calling behaviour as much as on signing; IPComms does not carry automated dialer or campaign-blast traffic, which is stated in the acceptable use policy.
