We had a similar issue however it was not spoofed calling. It ended up being a bad FXO line that was randomly going off hook and hitting the 911 dial peer which the dial peer label 911 was inserted into the calling number. The RTMT log was filled with the calling number coming from one of our gateways.

We have been having issues where we have 8865 phones registered through MRA locking out Active Directory accounts when a user password changes on the network. If the user does update the password in the 8865 in a timely manner it will continue to try to authenticate through MRA with CUCM. By default the parameters on the EXP E automated detection http proxy authorization failure parameter is 5 failures in 10 minutes locks it out for 10 minutes but then after that timer expires the 8865 proxies through again trying to authenticate. How do you prevent the 8865 trying over and over again when it has an old cached password. We have users that spend time in different parts of the country and may not be able to update their 8865 for 6 months. We are using

Interesting, our Jabber calls never failed. Is Jabber registered on-prem, expressway, or both? We used both command recommendations and worked fine.

We tested 12.5.1 firmware on the 8865 and still the issue. We also confirmed in Wireshark the only difference is the REVONLY with the shutter closed.
This is what we tested successfully for the workaround.
In the cube assign a SIP profile to the outbound dial-peer to Verizon with the following parameters and the calls should no longer fail.
request INVITE sdp-header Video-Attribute remove request INVITE sdp-header Video-Media modify "m=video(.*)" "" request INVITE sdp-header Video-Bandwidth-Info remove

We are hitting the same issue. We are running the same firmware and upgrading to the latest 12.5.1 this weekend will report back results. We found not all Verizon client calls were failing but was only Verizon clients that do fail. Who is your ITSP? Verizon is ours. One thing Verizon did tell us since we do not subscribe to video on those trunks that they saw requesting video codec from the 8865 in the invite but would ignore it. So we did test this to remove video requests in the invite at the CUBE and the calls do work when that is applied. So if not subscribing to video on the SIP trunks obviously Verizon is policing this based on the test with the cube.

We are doing this now and going with a cetralized HA cube design in our DC's clustered across the WAN. Call preservation is available in each DC if a cube were to fail. With a 1000 CC I would change your cubes to 4431's. Doing this approach reduces hardware and circuits costs, also reducing entry points into the network.. With this said the WAN needs to be able support the traffic.

Set the port as MGCP at the gateway. Build xlation with the attendant DN of the FXO port. Cross connect FXO to T/R of page adapter. Make sure signaling is loop. User dials xlation it will open talk path to page adapter. If you have zones you may need to insert another
digit.

Looking for a solid configuration for ATA 190 Fax using T.38 with SIP gateway. We have tried so many different options between CUCM and the IOS we still have issue randomly inbound and outbound.
Call flow:
ATA 190 (T.38)-->SIP-->CUCM-->SIP-->IOS2921-->PRI-->PSTSN

I have a user that keeps getting an MWI on their personal extension. I think MWI is flagged in another mailbox for that extension. Is there a report to tell me if that extension is flagged for MWI in another mailbox?

Hello - I'm currently running CIPC 8.6.3.0 on BE6K 9.1, the issue I'm having when bringing up the call stats with the ? it is not showing AVG Jitter, MAX Jitter, and RxDisc. Is there a parameter that needs to be toggled on to receive this information.
