Hello Experts

in SV9100 PBX,calls from IP phones to digital or analog phone are established but "sometimes" NO VOICE

I have sv9100 pbx with 50 license IP phone . the system works normally but some times I got some calls without voice between the IP phone and the ( digital or single phone ) .
in system alarm report I got this error ( IP collision 3 ) every 1 mint . there is no IP conflict in the network.
10 -19 IP extension only
10 -54 5103 42
15 -05 50 peer to peer on
84 -24 03 Alow
28 711 / I try with codec 722
I make a continuous ping with the system SV9100 IP when the error occurs I loss the ping with the DSP IP ( the IP in command 84 - 26 ) . just when the call failure occurs .then the ping back normally .
the network teem confirms that there is no problem in the network .
pls advise what we can do to solve this problem .
Thanks for you all

IP collision. It wouldn't be giving this if it wasn't an IP (or UDP) issue of some flavor. Well, isolate the system from that "perfect" network and see if it duplicates on your own little test network. If the problem goes away (or doesn't) I think you know where the problem lies. I would also look at 10-58 to make sure your internal network scope is setup. Using 722 on an internal network, UGH.

According to NTAC it's something to do with Cisco Device Probing or something to that effect.

Get into DIM and list out the ARP cache. You will see an entry with quad zero's and it will be associated with a MAC address of a Cisco device. Ask the network folks to isolate the 9100 from that device. The 9100 does NOT like quad zero's.

NTAC would point you to this document.
