Hello,
Welcome to 3CX
Please tell me more information about your device and network
most propably it's firewall or nat
try to close firewall

 

[zlambert]

Cisco router
linksys voip router
computer with xp and 3cx
2 linksys spa921 telephone
1 analog phone via the linksys router
1 porttech mv-370 voip-gsm gateway

all other call is fine.... so if i call out via my Voip provider, than I can speak (I had some call more than 8 minutes without problem)
but if someone call me about 40 sec and the call terminated.... I saw the log file and there was: ACK is not received, and call terminated...

so try with only one router, or should I turn off the firewall You think?

in test time it's better to turn off firewall
also use one router minimize nat issues

What is your voip provider
