Add VLAN configuration support to prevent call drops
This update adds comprehensive VLAN support to prevent the common issue of calls dropping after 30 seconds in multi-VLAN environments. Changes: - Added new menu item "Configure VLAN Subnets" in Server Settings - Created configure_vlan_subnets() function to manage VLAN configuration - Updated pjsip.conf generation to include multiple local_net entries - Added server IP address as comment in transport sections for reference - Persist VLAN settings (HAS_VLANS, VLAN_SUBNETS) in config file - Updated script version to v0.9.8.8 Technical details: - The generate_pjsip_conf() function now builds multiple local_net entries when VLANs are configured - Each VLAN subnet is added as a separate local_net line in the transport configuration - Server IP is detected and documented in transport sections - Transports continue to bind to 0.0.0.0 for all-interface listening This fixes the issue where Asterisk would treat devices on different VLANs as external connections, causing NAT issues and call drops.
