Obviously the SIP Client wants the ACK within a certain amount of time.
If it does not receive the ACK within this time, it hangs up.
Thus, I suggest configuring the SIP Client to wait a little bit longer.
Which SIP client is it? A softphone or a gateway?
Usually gateways (eg Cisco) can be configured to increase
retransmissions and have a higher timeout.
