Brazil seems to have an unusual numbering format! Luckily, we like a challenge here
The most simple digitmap I can come up with is:
Physical Interfaces > LINE Port > DigitMap:
([2-5]xxxxxxx|[6-9]xxxxxxxx?|0[1-9]xxxxxxxxxxxx?|00xx.S3|xx.S3)
In order, this matches:
Eight digit numbers with first digit 2 through 5.
Eight or nine digit numbers with first digit 6 through 9.
Thirteen or fourteen digit numbers with first digit 0 and second digit 1 through 9.
Numbers of any length starting with 00, with delay reduced to three seconds.
All other numbers with delay reduced to three seconds.
There are no short codes (emergency numbers etc ?) included in the digitmap, but they will be matched by "xx.S3". Normally, I would prefer to route emergency numbers through the Phone Port OutboundCallRoute. This may already be the case or you may be user a voip provider for this rather than PSTN.
OBi Line Ports assume the worst case scenario when it comes to your PSTN line. A long line may need long DTMF tones when dialling. If your PSTN line is ok, then you could try reducing these settings from the default 200 to something like:
Line Interfaces > LINE Port1 > LINE Port > DialDigitOnTime: 80
Line Interfaces > LINE Port 1> LINE Port > DialDigitOffTime: 80
PSTN line dialling will never be as fast as voip, but the above should achieve something like "normal" delays.
If there are a few numbers that you dial over PSTN a lot, then you might consider configuring them as speed dials using trunk format:
li(01234567890123)
Using trunk format avoids digit maps and all call processing and simply sends the call direct to line – you still have to wait for all the DTMF tones to be sent.
