asterisk users - Mar 2009 - early dial (or overlap dial) and Asterisk 1.2 vs. 1.4

Hi,

I am testing some IP phones (eg. GXP2000) and noticed that the "early
dial" feature works fine with Asterisk 1.4 but not with 1.2.

"early dial" is when digits are sent immediately, one by one, and
Asterisk replies with a "484 Address Incomplete" and waits for the
next digit until a match is found. This is a very useful feature where no dial
patterns have to be set on the phone and the calls are sent without having to
press the "send" button or the # key.
This feature does not work with Asterisk 1.2 and I get a "reason
code:481" on the IP phone.

It seems that if one sets pedantic=no in 1.2 then the "early dial"
feature works. However, I need pedantic=yes for the # digit to work.

I have a mixed cluster with both * 1.2 and 1.4 and would like to avoid the
hassle of upgrading the 1.2 servers.

Is there a quick fix/hack?

Versions: Asterisk 1.2.30, Asterisk 1.4.21.2

Thanks,

Vieri

Hi,

The part of pedantic=yes that you need to make '#' work is URL
encoding, unfortunately it comes with a whole load of other baggage
that breaks a lot of different things. A simple fix might be to
comment out the parts of pedantic=yes that you do not need in the
source code and re-compile - This does of course assume some knowledge
of C.

I used to have a patch which added a urlencode=yes/no feature to
asterisk 1.2.x, but I just looked, and I no longer have a copy. If I
am not mistaken, Asterisk 1.4 changed this code quite significantly.

Regards,
Steve
