I have a problem with FXO cards, I have sangoma 4 FXO, I am writing agi for Telebanking Sys.(with java-asterisk) i need to get 12 digits number from pstn, and now my problem: when user calls fxo cards and enter digits, if he/she enter digits too fast the call will drop and it cant get the digits, but if he enter digits in normal speed there is no problem. i don't have this problem form softphones (SIP Messages), i think it is because of FXO cards, now i want to know how can i solve it. 1) is it because of analog card, would i have this problem on E1? 2) is any config on sangoma's driver or zapata.conf to change the getting speed? Thank you in Advanced.
