Hi Experts
I am a new Pie in Sophos XG and we have implemented a new IP PBX in our company the design is to allow our work from home and international sales team to call and receive calls from clients all over the world via many SIP trunks
I have successfully implement and configure our SSL VPN and use UDP 8443 for best performance
the main issue I am facing is that all of our international sales team can't call
the traffic get dropped once they try to call
the connection established from their side correctly and they able to use local services like share file but once they start a call the connection start to get unstable
all my local and home team do not face this issue so I suspect that may our ISP or their ISP try to intercept the traffic to get to our calls or I don't know exactly what is going on.
I don't know what should I do
any screen shoots or more details will be provided upon your request
Please Help !!
Thanks
Mohamed
