Hello,
Have any of you had an experience with Grandstream BudgeTone phones? My outgoing calls are being dropped after 16 seconds. My system looks like this:
Grandstream phone ---> SER sip proxy ----> VEGA 50 SIP gateway. x-lite softphone ---->
When i make an outgoing call from my softphone it works fine. But not with ip phone. After 16 sec. my VEGA gateway disconnects the call. After talking to VEGA customer support they told me that my ip phone is not replying back to VEGA's ACK requests, and eventualy after 26 sec. VEGA dropps the call. Does anyone out there have a similar setup or ever experienced such a problem? I am running the latest firmware on my ip phone.

There is no reply to ACK and the gateway does not send any ACK in this case. The ACK is generated by Grandstram and x-lite. Use ngrep (or similar tool) to check whether the grandstream phone gets 200 OK and generates ACK.

OK,
i used ngrep to listen to dst port 5060 and this is what i got. Can anyone look at it and try to help me out?
