🔧 Dialplan Configuration

How It Works

You dial: 093364626141

PBX strips: 09 prefix

PBX adds: 1 for North America

Sends to trunk: 13364626141

Callcentric dials: +1-336-462-6141

Pattern Matching (Asterisk Format)

_09NXXNXXXXXX    = 09 + 10-digit (3364626141)
_091NXXNXXXXXX   = 09 + 1 + 10-digit (13364626141)
_09011X.         = 09 + 011 + international
_09[2-9]11       = 09 + service codes (411, 611)
_911             = Emergency (no prefix)

Legend:

• _ = Pattern start


• N = Digit 2-9


• X = Any digit 0-9


• . = One or more digits


• [2-9] = Range of digits

🚨 Common Mistakes

❌ Wrong: 93364626141


Missing leading 0 - won't dial out

❌ Wrong: 0093364626141


Too many zeros - won't match pattern

❌ Wrong: 913364626141


Missing the 0 - won't route

✅ Correct: 093364626141


Perfect! - will dial out

✅ Also Correct: 0913364626141


If you prefer including the 1 - also works!

🛠️ Troubleshooting

"Cannot Complete Call"

Check:

Did you use 09 prefix? ✓

Trunk registered? Check Trunks Manager

Channels available? Check Channels tab

All channels in use

Invalid destination number
