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.
