[Asterisk-Users] No ringing tone

[Lal, Deepak (Contractor)]

I have the following setup:

AnalogPhone1--TDM400P-ASTERISK---via SIP---Softswitch--------POTS Phone2

When I call from AnalogPhone1 to Phone2 I hear a ringing tone and all is well.
When making a call from Phone2, I get a dial tone  but after dialing the number
I hear nothing (no ringing tone). On Asterisk console it says that a call is
coming in and that it is ringing Zap/2. I can also hear the AnalogPhone1 ring! -
