Yes..... It's just they are un-registering sporadically even during
calls.
This is just a layer two switch so everything goes over the Gig Do1q
trunk.
I'm going to replace the switch and see if that fixes it.

Do the phones ever register? or just continuously reboot.
In your config I don't see the VLANs referenced in your access and voice
vlan port config. can you post a sho interface trunk?

I'm really going to show how dumb I am but I'm too close to the problem.
I have a 3560 48 port 10/100 PoE switch that connects about 6 phone back
to an other 3560 via SX.
The switch / phones I'm having problems with keep loosing connections
and therefore the phones keep reseting.
I found the one switch with err-disable do to flapping. So I replaced
the SX and put it in a different Gig sfp slot.
Still having the issue.
Look to be a broadcast storm by the link lights. So I unplugged ports
until the lights went back to normal. Follow the cable back to a phone
--> PC. Plug it back in and the lights still looked fine.
telnet into the switch and I'm seeing the gig link Broadcast and
multicast increment at a rate of `100 per sec. NO other switch ports
are incrementing anywhere close to this.
Is this a bad switch? Do I have a bad run of fiber? What can I do to
trouble shoot more?
