Hey nanocomputers...
mmm looking at your logs compaired to a normal call to a good call log there are a few major things that stand out...
My settings
My extension = 400
Number to call = 0418603000
Prefix to get line out = 0
My Linksys PSTN box extension = 10002 and 10001 - I HAVE TWO OF THEM setup to use line 2 before line 1.
A good log

Looking at your logs
** Working from the bottom **
1 - call from EXT 1000 to number 0614024168 (is your prefix 0??? because its not trying to call your PSTN box... its trying to call an extension with that EXT number.)
2 - the call is then stuffed from this point....
QUESTIONS
Can you please confirm these details...
- Your prefix to call out is 0 - I think it may be something else
- You are dialing the prefix before dialing the number....
- The number you are trying to call is 0614024168
** If you are trying to call 0614024168 then you need to put the prefix of the outbound rule in first... Mine is 0 but yours may be different...
** So the number to be dialed may be 0061402168
It doesn't look like 3CX is seeing that prefix and linking it to the outbound rule!...
To check your prefix go
OUTBOUND RULES > MANAGE
read the line column 'Number prefix'
If you are puting the prefix in then have you upgraded the system recently?
If so just delete the outbound rule and recreate it...
The outbound rules can become corupt during upgrades... This is stated during the upgrade process!
Post back how you go please!
