Thank you Jamie.
Yeah, I had already looked at the guide and the ports, but the list seemed rather long, so I was wondering if someone already had an acl built with all the needed ports to save some time.

I'm looking for a sample ACL to allow CUCM and Unity Connection traffic only. We are providing voip service to a near by hospital and we are wanting to restrict traffic, while allowing traffic for voice services.

Same issue here with 8845 phones, DMPs and our AIR-CAP2602E-A-K9 aps. Older aps and 6921s, 9971s are not locking up. The only way to restore service is a shut and no shut or unplug the device and reconnect it.

Just an update.
My problem was actually the 7925 phones were grabbing an ip address on the wrong vlan. Once they grabbed an ip address on the correct vlan, they registered correctly.

There are 70 working 7925 phones, however we are installing 100 + new 7925 phones and 90 % of the phones are failing to register.
Call manager 9.1.2
The phones are grabbing the correct ip address, subnet, gateway and tftp address. They are identical to a good working phone.
The App Load ID on the new phones is "CP7925G-MFG-F.2.LOADS" , once a phone registers the App id shows
"CP7925G-1.4.3SR1.2.LOADS".
Messages that are on a failing phone are below.
Downloading AOM (1/1)
AOM installation failed
Status messages:
DNS unknown Host
CiscoCM1
Waiting on MIDP module installation
AOM installation failed
TFTP timeout
TFTP timeout
The phones that are failing are using the same tftp server that the good phones are using, however there is not any call managers listed under "Settings - Device information - Call manager".
I'm not seeing a common denominator with the failinig phones and the working phones.
Any help would be greatly appreciated!!

Thanks Brian,
Enabling web access resolved my issue as well.
Push to talk would work with my 9971s via informacast, however sending messages via informacast did not. Enabling web access fixed it!!!

Is the phone grabbing an ip address from the same subnet everytime? You can try setting the lease time to infinite. See link below. https://supportforums.cisco.com/discussion/12218921/cisco-ip-phone-6921-keep-displaying-ip-address-released Hope this helps. Please rate helpful posts. Thanks.

Hello mohammad, RJ11 will use pins 3 & 4. Link below shows the pin out for RJ11 http://www.allpinouts.org/index.php/RJ11_Telephone To verify your RJ11 wiring, plug the RJ11 into an analog phone and go off hook. Hear dial tone, you know you are good. Plug the RJ11 into the fxo port. See document below for troubleshooting Analog voice interfaces. http://www.cisco.com/c/en/us/td/docs/ios/voice/monitor/configuration/guide/12_4/vt_12_4_book/vt_anlg_vc_tbsh.html#wp1054314 Hope this helps.

I mi found the following info at https://supportforums.cisco.com/discussion/10874991/linksys-wrp400-voice-configuration "Once you access the Voice Admin menu and provision your device for your VoIP provider, access to the Voice menu is subsequently "Locked". Your VoiP provider's system has set a new unique password for the Voice menu once the provisioned device has synced with your providers system. You should be able to get that password from the control panel on you VoIP account profile under "equipment" or a call to support or an e-mail request should garner the password. The Login will be "admin" and the password provided will get you back into Voice menu system. You will also need this password if you want to reset the Voice features back to factory defaults. Because of this system it appears that a WRP400 cannot be unlocked by merely using the reset button. " Hope this helps Please rate helpful posts Thanks
