SIP FAQ : SIP Protocol Operation :
Are ACK requests retransmitted? |
| No. An ACK is sent when a response retransmission is received. Reliability is achieved because the response is retransmitted until an ACK arrives, and the ACK is retransmitted on response retransmissions. ACK is only used for INVITE. | |
