I need to use a SIP port other than 5060 to work around a provider problem. But some messages - I noted ACK and BYE - are still sent to 5060. Zoiper 3.9 for Windows.
The Wireshark capture below shows the problem:
Bug or user error?
It turns out that X-Lite does the same thing. I guess Zoiper and X-Lite use the same SIP stack.
Can you share the full packetcapture with us please ? (You can send it to firstname.lastname@example.org if you don't want it shared publicly).
Capture emailed as requested, thanks.
has this been fixed, as i am recieving the same issue in zoiper5
I'm the original poster. Nothing was fixed as far as I know. I began to suspect that the behavior was actually correct according to the SIP standard since I saw similar behavior outside of Zoiper.
