[Freeswitch-users] Invalid and unreliable DTMF

I am facing an issue where DTMF digits are wrongly captured or getting
entirely missed from being detected.

*Sangoma *A116 / A108
*Freeswitch Version 1.2.14*

perl ivr scripts using *perl ESL*
PRI lines from Indian operator.

However the same script and same configuration works perfectly well on
Freeswitch *version 1.0.7*. Also none of the versions gave any issue when i
test by simply using mod_sofia and an extension on x-lite.

I viewed the entire change logs from version 1.0.7 till 1.2.14, there are
no changes on DTMF since 1.0.7

Are there any possibilities that telco plays a role as well in such DTMF
