hello everybody . im working on a small project ,, but i have a problem . the project is connecting an analog phone to an avaya ip office through smartnode . im wotking on 2 smartnode 4524 A and B, A is connecting to the avaya office through the FXO port , then its connected to B through ethernet port . on the other side an analog phone is connected to B through FXS port . i must be able to call an extension on the ip office through the analog phone . i did some configuration to be able to connect to the ip office : if i call the digit "8" from the analog phone , i get the dial tone from the ip office , so im conntected to it .then i must be able to call any extension on the ip office . But when i try to call an extension it doesnt work : for exemple if i will call "154" , i press "1" , i dont get any new tone ,, its always the dial tone present . I think its a DTMF problem . How can i fix this problem ? Thank you in advance .
