Found a new one today, wondering if anyone's seen this before.
I have two ring groups. 5075 and 5091. 5075 overflows to 5091 after 15 seconds. Both are set to continuous ring.
All the members of 5075 are in 5091. 5091 also includes three additional phones. For this example we'll say 1000-1004 are in both groups, and then 1201-1203 are also in 5091.
If disable the overflow, 5075 rings just fine. If you call 5091, again, all its members ring at the same time.
However, if you let 5075 overflow to 5091, here's what happens: Extensions 1000-1004 will all ring once at the same time. Then 1201-1203 all ring at the same time, then 1000-1004 once, then 1201-1203 once, repeatedly until 5091's overflow timer kicks the call to voicemail. If your phone is ringing, you can pickup the call during the ring, but if you answer just after the ring, you get dial-tone. Which is really annoying because the end-users take that fraction of a second to grab the phone, so end up getting dial-tone.
Anyone ever seen this?
Tried blowing both ring groups away and re-creating them, but got the same results.
