Have an ASPIRE that is running all IP phones about 60 phones across 4 buildings with multiple switches through out. All same subnet

getting reports of one extension dialing a number and getting another extension. (not a call forward issue).

Any one run into this?

Apirenet or all off same system?

same system, remote sites are bridged wirelessly but it doesn't seem to be limited to intersite. I have one instance where 3 phones on same POE switch phone A caller, phone B inteded recipient, phone C actual called. but have it phone at switch A calls phone at switch B but gets phone at switch C

Sounds like a messed up F routing table somewhere.

no f routes in place....and it is intermittant.
I am thinking somehow the phones are resetting intermittantly and getting a dup IP address

Are the IP's static? DHCP is a nightmare.

no static, using DHCP to dole out ip and server info.

Shouldn't be an issue then. Is it a possible bad dial pad on the phone?

would be several phones all at the same time

Well, what I have seen in the past on networks is that if a switch or router that is storing the mac/ip data is freaking out it can and will route things very strangely.

Trying to get the customer to log events so that way I can hopefully see a ryhme or reason. then star tlooking at switches and/or routers.
