 I am having an issue with multiple Yealink W60B and W53H on 2talk.
After a period of time (looks to be about an our) the handsets stop receiving calls but can still make them. If I call from a T46S I get "busy". The handset is still within range etc. restarting the phone does not change anything, restarting the W60B  base fixes the issue, but temporarily.

> For reference this is running through a Ubiquiti edge router, so sounds like it could be a SIP ALG issue?

 

No I think more likely just a connection state tracking timeout like I described earlier.

 

From memory, on an EdgeRouter in the webUI you'd be looking under config tree -> system -> conntrack -> timeout -> udp

 

I'd try setting that to 180 and also make sure qualify (options) polling events from 2talk are not disabled. Ie make sure the checkbox called "Disable Qualify (OPTIONS) polling events for this line (This is used to track the registration status)" is NOT ticked - this is under 'Voice Quality & Networking' in their web portal.
