Q: I'm getting "Could not initialise SIP engine..." when running the Minipax softphone.
A: There could be two possibility:
1. Minipax softphone detect no internet connection. Minipax softphone always detect for internet connection, if you don't have internet connection Minipax will failed. Make sure you check for internet connection by opening Internet Explorer. If you are sure Internet connection is established, make sure that Minipax softphone is allowed/unblock by Windows Firewall or other firewall.
2. You use STUN but Minipax cannot reach the stun server or the stun server is not responding. Try using another stun server or don't use STUN and UPNP at all.
Q: I'm getting "Registration failed. Reason: Invalid realm"
A: This is caused by you supplied realm which is don't match with realm that sip server supply. If you supply sip domain name as your sip server, Minipax will automaticly add this as realm. If you supply sip ip address as your sip server, you need to enter the realm name.
To get the realm information please consult to your sip server vendor or snif the SIP messages with ethereal packet trace.
