[Asterisk-Users] No dialtone in a E1

[Marco Castillo]

Hi, I'm having a little problem when trying to make a call from asterisk. I
connect a SIP phone to asterisk, and in the asterisk box I have a TE110P
card connected to a E1. When a SIP client makes a call through the E1, I
received no dialtone in the SIP client.
In the same manner, when somebody from the POTS network makes a call to a
SIP client (through * and the E1) he doesn't receive the apropiate tone of
call progress. Does anyone has some ideas about this?
