Sonicwall VOIP setup

For the SonicWALL routers, we recommend the following adjustments:

1. Disable SIP Transformations

2. Enable Consistent NAT

3. Make sure UDP timeout is set to a minimum of 300 seconds (globally)

4. For JIVE: Create rules to allow ANY UDP traffic to (LAN -> WAN) and from (WAN -> LAN) these Jive IP blocks :

– with a net mask of
– with a net mask of
– with a net mask of

These adjustments will generally resolve 99% of SIP-signaling issues on SonicWALL-routed networks. If not, please let us know.
