Hello TP-Link Forum users,

I have just purchased the TL-R470T+ load balance router and having a few issues resolving incoming VOIP calls that are dropped after 1 minute and 5 seconds.
No problem with SIP configuration as I tested it on another router.
The following has been tried without any success.

Disabled SIP ALG
Increased the packet rate and also disabled UDP Multi-Connection Flood
Increased the packet rate and also disabled UDP Stationary Flood
Added an access rule to allow WAN (Any) to LAN (IP) - UDP on port 5060 - 5062 ( port being used)
Added the IP to a DMZ........


Would really like to know the simple fix as I appear to be overlooking it.

Thanks
