Caller IDs, carriers and spam protection

How numbers are chosen, capped, watched and rested; the pbx.im and Telnyx trunks.

Carriers

Relay calls leave on pbx.im, Parley calls on Telnyx, the CRM softphone on Bitcall or pbx.im (Settings → Carrier). Each caller ID belongs to one carrier; picking the number picks the trunk. Numbers are managed under Call Center → Numbers.

Rotation and caps

• Country-aware: UK leads get UK numbers, US leads the US number.
• Sticky: a lead you have called before sees the same number again.
• Mobile numbers are weighted 2×.
• Per-number daily cap (Settings → cliDailyDialCap, default 300).
• Per-lead attempt cap (3/day, 60 min apart).

Caller-ID health

Every hour each number's answer rate, hang-up-within-5-seconds rate, straight-to-voicemail rate and conversation rate are compared with its own 7-day baseline. A number that looks burnt is rested automatically for 3 days (never the last number of a carrier) and managers are alerted; the Carrier report shows the verdicts and lets you Rest or Unrest by hand.

Protect our numbers checklist

• Register every number with Hiya Connect and Truecaller Verified Business (links on Reports → Sources).
• Keep one test handset per UK network (EE, O2, Vodafone, Three); call it from each number once a day and note what the screen shows.
• Keep the caps on. Don't dial one number 500 times a day.
