===== Ubiquiti UDM Pro=====

Advanced Settings for Dream Machine Pro (UDM Pro).

Search for SIP or Timeout. Adjust as below. 

Under **Firewall Connection Tracking** (bottom of below image), make sure that **SIP** is not enabled. If there is a gray box showing SIP, that means it is enabled and you must click the **X** to dismiss/disable it.

**Timeout** should be set to a number greater that 600 seconds. 620 is recommended as our phones use 600.
