An AI sales agent's hosted PBX quote, checked before it goes out

An AI sales agent prepares a monthly quote for a Texas public-sector customer that wants Granite hosted PBX (HPBX) seats, voice paths, call center seats and IVR under the Texas DIR contract price list: the seat plan, the contract term, the usage bundle and the monthly and one-time charges. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published price list and returns a verdict, every reason and the figures it computed.

Scope: Granite hosted PBX (HPBX) quotes on the Texas DIR contract price list: seat plans, usage bundles, voice and SIP paths, call center seats, IVR, contract term and stated charges. See everything this validator covers

This validator models hosted PBX monthly quotes as published in Granite's Texas DIR-TELE-CTSA-012 Attachment B-2 price list (read October 7, 2026), not just the scenarios shown below.

  • Seat plans and add-ons — the six HPBX seat plans (GRT HBPX 1 to 6), the unlimited local, long distance and domestic usage bundles per seat, HPBX voice paths, SIP call paths, call center seats (entry, medium and highest level) and IVR licenses, each at its published monthly price including the DIR administrative fee.
  • Checks — these services are listed for 2-year and 3-year terms only; call center seats have a 3 license minimum and IVR a 25 license minimum, and both must include Granite SIP, Hosted Voice or Hosted PBX service; call center seats need a seat level; the stated monthly and one-time charges must equal the published prices.
  • Approval — configuring a non-Granite device is listed as subject to technical review at $206.96 one-time per device, so a person confirms it.

Any hosted PBX quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: phones and other equipment rental, Hosted Voice line bundles, broadband and data services, wireless, long distance and toll-free usage rates, taxes and regulatory surcharges, other states and Granite's non-contract prices.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Minimums on call center seats and IVROnly with care
A minimum quantity per product is a validation rule on each line, and it is easy to miss one when seats and IVR are quoted together.		Both minimums are checked on every call, together with the other rules.
A product that needs a different service on the same quoteOnly with workarounds
Call center seats and IVR must come with SIP, Hosted Voice or Hosted PBX service; this is a dependency between lines that a rep can break by removing the other line.		The dependency is checked whenever any line changes, and the answer lists it with the other findings.
Terms that only some services offerOnly with care
The allowed terms differ by service, so a term rule is needed per product family and kept in step with the price list.		A term the services are not listed for is a blocking finding.
A stated total that leaves out an add-onOnly with workarounds
A rep types the monthly total; comparing it with the sum of seats, bundles, paths, call center and IVR is a separate price rule.		The stated monthly and one-time charges are compared with the computed ones on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a monthly quote for a Texas public-sector customer that wants Granite hosted PBX (HPBX) seats, voice paths, call center seats and IVR under the Texas DIR contract price list: the seat plan, the contract term, the usage bundle and the monthly and one-time charges. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published price list and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote Granite hosted PBX on a 1-year term for the customer: 40 seats on HPBX 3 (full features including mobile app). The quote states a monthly charge of $1,913.08. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The quote uses a 1-year term, but Granite lists these hosted voice services for 2-year and 3-year terms only. Call center seats have a 3 license minimum; the quote has 2. IVR has a 25 license minimum; the quote has 10.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for minimums on call center seats and IVR, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the contract term to 3-year, the call center seats to 4, the IVR licenses to 25 and the stated monthly charge to $2,620.11.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's total, $2,620.11, matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
