It's seems the process of consistent NAT does not do what it's supposed to across the board therefore I've recommend that it is turned off across our knowledge base.

Disable SIP Header Transformations and Enable Consistent NAT

SonicWALL SIP ALG is called SIP Header Transformations, this should be Disabled and Consistent NAT should be Enabled:

Create Outbound NAT Policy and Disable Source Port Remap

In some cases the SonicWALL will remap the 5060 and 10000-20000 UDP source ports causing one way audio and calls dropping after 30 seconds.

To resolve this, create an inside to outside rule like the following:

Original Source:
Translated Source:
Original Destination:
Translated Destination:
Original Service:
Translated Service:
Inbound Interface:
Outbound Interface:

PBX Private IP
IP of the WAN interface (X1 IP for example)
Address Group for our SIP servers (52.5.220.123 or 54.200.236.200)
Original
Service Group including 5060 UDP and 10000-20000 UDP
Original
Any
WAN interface (X1 for example)

After that go to the Advanced tab and check the box for "Disable Source Port Remap" and click OK.

Once completed the PBX will always use the proper source ports on the WAN side.

Create Access Policy with Increased UDP Timeout

Most often seen in cloud deployments you will see phones going REACHABLE/UNREACHABLE with complaints of calls going directly to voicemail and BLFs not lighting properly.

To fix this add a LAN to WAN Access Policy as follows:

From Zone:
To Zone:
Service:
Source:
Destination:
Users Allowed:
Schedule:

LAN
WAN
SIP (UDP 5060)
Any
Any
All
Always On

Navigate to the Advance tab and increase the UDP timeout to 300 seconds, once saved phones should remain REACHABLE.
