SCN one way traffic

[emmitt2727]

I have a 9.0.0.o 829 and a 9.1 with SCN between them. We are only getting oneway traffic all of the sudden. It worked fine for several months and then just stopped. I can ping both direction, the IT staff has verified all the ports are open, and I have been through the whole setup with my tech support people. All account point to the fact that it should work. Site A can call Site B just fine. Site B I can watch dial, but it kills the call before it gets to the trunk. It tells me no channels are available. We have double checked routes, short codes, lines and see nothing causing it to fail. We rebooted several times. Any ideas where to look next?

Network, network, network...always is. I'll wager that monitor shows "CALL LOST (CMCauseNetworkOOO)" for the failing site, did I mention it's always the network, IT will end up eating humble pie

How can I prove that to them?

Sometimes you need to go as far as forming your own link with your own routers, when it works you don't need to prove anything more

SCN issues are always the network (there are not enough options on the IPO to get it wrong if you wanted to).

It worked fine for several months and then just stopped

did anything change on the IPO (check audit trail) if no then it is the Network

the IT staff has verified all the ports are open

I wish I had a £ for every time that has proven to be a lie incorrect

Agree with everyone. Always the network.
Had this come up "we swear nothing changed on the network, it's the phone system". really? "oh...well, we did turn on intrusion and deep packet inspection the same day it stopped working...". uh huh.

We didnt change anything on the Network"

Can the network guys provide any sort of Audit trail to show this to be the case (We can with the IPO )?

Site B I can watch dial, but it kills the call before it gets to the trunk.

If the call is REALLY stopped before it gets to the trunk, then it's not the network. I suspect that, if you're watching System Status, you're simply not seeing it. A trace from Monitor will tell the tale...
