Hi,

I'm using your latest Blink lite version on a windows 7 (64 bit) OS PC
which has 2 interfaces (WAN and LAN).
I'm trying to register a client to an IP PBX from the LAN but the
registration fails. The PC has IP address 10.0.49.235 and the PBX
10.0.49.231.

>From the logs I've noticed the VIA field is set wrong , is set

It seems there is an issue with the Blink client as the zoiper or x-lite
client does not have this issue.

Dinu
