Hola! I'm playing with libss7 and found that if I make a dialplan like: exten => 08231451010,1,Answer ... the result is: 105 12.024960 2146 -> 639 ISUP(ITU) IAM (CIC 2) 107 12.028962 639 -> 2146 ISUP(ITU) ANM (CIC 2) 109 12.065962 2146 -> 639 ISUP(ITU) RSC (CIC 2) 111 12.068958 639 -> 2146 ISUP(ITU) RLC (CIC 2) 113 12.103963 2146 -> 639 ISUP(ITU) RSC (CIC 54) It seems that the switch I'm connecting to doesn't accept ANM without a previous ACM. Who is wrong? asterisk (libss7) sending ANM directly or the other switch not allowing that? Thanks! -- Horacio J. Pe?a horape at compendium.com.ar horape at uninet.edu
