[Freeswitch-users] Invalid and unreliable DTMF

Hi, I am facing an issue where DTMF digits are wrongly captured or getting entirely missed from being detected. Environment: *Sangoma *A116 / A108 *Freeswitch Version 1.2.14* *mod_freetdm* 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 issues.? Thanks,
