Issue in voice traffic

Hi iftikhar haider,

If you are able to ping your local Voice server from the Branch office to head office please try by adding snat as per the below information :

Add an IPsec route at the Branch Office and apply a Source NAT policy on its Sophos Firewall-initiated traffic so that its source IP address is internal:

1. Sign in to web admin of Sophos Firewall.
2. Click admin > Console and press Enter.
3. Enter your password.
4. Select 4. Device Console and press Enter.
5. Run the command below to add an IPsec route to the host destination.
   
   console> system ipsec_route add host <IP Address of host> tunnelname <tunnel>
   
   ( here you have to add voice server IP in <IP Address of host>)
    
6. Run the command below to NAT the Sophos Firewall traffic to the desired public IP with the private LAN IP:
   
   set advanced-firewall sys-traffic-nat add destination <Destination IP/Network>  snatip <NATed IP>

              (here you have to add <Destination IP/Network> as your voice server IP > and snatip <NATed IP> as Sophos LAN IP)

Make sure you have LAN-VPN and VPN-LAN firewall rules on both the Sophos XG and apply NAT on VPN-LAN rule to troubleshoot the issue

This might help you 

Dear Is it possible that you can tell me these steps in GUI mode

Thanks...
