[asterisk-users] ISDN Cause codes

[Don Kelly]

What is the source of the numbers you are calling? Are they
previously-verified numbers from your database? Are some of them
fumble-fingered manually-dialed calls? I'm pretty sure that I goof on more
than 3% of calls that I manually call. Have you researched some of the
failures (examining the numbers that were attempted to be called)? I don't
really see a problem with what you're reporting.

Subject: [asterisk-users] ISDN Cause codes

Hi All

Just been looking at stats for one of my sites, and I'm conserned about 
the number of error cause codes being returned from the telco

for example

12000 calls processed

131 are cause code 31* normal. unspecified.*

139 are cause code 28 * invalid number format (address incomplete).*

112 are cause code 1 *Unallocated (unassigned) number.

*this adds up to about 3% of calls not completing.

there are various other codes including 17 busy 34 channel unavaliable 
and 44 requested channel unavaliable, which add up to another 1%.*
*
the telco says there is no problem with the line, I'm trying to 
understand what the problem could be

now  alot of calls complete OK so I don't think is my configs

Any advice would be appriciated

Versions
asterisk 1.4.21.1
zaptel 1.4.12.1
