I configured E1 R2 on AS5350(12.4T),when I tried to send the call to E1 from VoIP, the call can go through, but the PDD is too long. The caller got long silence befor ring back tone came. From the log, AS5350 got Seizure ACK then spent more than 10s to get the ring back from the Switch. Is there any way to reduce the delay? Thank you.
