I have a script that creates fifo's on the fly, and at one point i had it worked with call waiting, but i don't remember what i did at that time, nor what changed (months and months ago) however, i cannot seem to get Calls in FIFO to trigger call waiting on the phones that are set as Members of that FIFO Queue.

Basically if i have 2 calls come in, and i answer one, i want the 2nd call to ring through to my phone (as well as others) even though i am already on a call, Call Waiting currently works if i dial directly to the device (say extension to extension calling) or even by routing a call straight to an extension, then trying a second call to that extension.

I have tested this with the same results on the following

Aastra 6757i (Firmware 2.6.2019 and 3.3.something)

Cisco SPA525G2

Polycom SoundPoint IP 550

Jitsi SoftClient

X-Lite Soft Client.

The behavior is the same regardless of the endpoint, i even tried creating loopbacks in order to trick the system, but from what i can tell, the server isn't even attempting to call the phone that's currently busy.

The problem is that we have clients who get off one call, and have to wait 30+ seconds (fifo_member_timeout) before they can answer the next call, I've tried adjusting lag and it seems to have no impact.

I'm working on getting a wireshark of this behavior, but i just wanted to reach out and see if the current behavior is in fact the correct one, and if not, or if there's a solution what i can do about it.

Have i overlooked something ridiculously small?

Here's what my fifo list <id> looks like
