Scenario: 9 servers connectec to each other over IAX trunks. Users used to call to remote extensions and remote Conferences (meetme) via IAX.
Problem: all extensions from one server (just one) when try to attend remote conferences had problems with PIN validation. If they use their local conferences the problem doesn’t occur.
All servers use same OS (Ubuntu 10.04 64 bits), same Asterisk version
(18.104.22.168) and same configurations.
DTMF type is rfc2833 and jitterbuffer is off. Codec is gsm and trunk=yes in iax.conf.
I did some tests with read cmd and discover that If user press 4
digits, only 3 digits are recognized. If user press 5 digits, only 4
are recognized and so on. Looks like the last digit is always ignored.
