Does anyone know if the newer ISR 4K series of routers is backwards compatible with CUCM 8.6 using MGCP; and if so, is a COP file required for CUCM?
After doing a little research it appears that the 4400 series does not support FXO/FXS lines and looks like it is primarily being marketed as a CUBE router used for establishing SIP trunks to an ITSP. I am mainly curious about the 4351 router and its capabilities as a voice gateway.
Any info regarding MGCP compatibility using T1/PRIs in CUCM 8.6 would be appreciated! Thanks again.
This is all I could find on Cisco's website:

The 8.6 version listed here is an ES version.

Can you send me a link where I can download that engineering special, or do I need to open a TAC case?

You need to contact TAC for publishing the link to download ES.

Hey Guys,
i understand this post is an year old, but I am trying to add a ISR 4351 to CUCM 10.5.1.10000-7 but cannot find it listed on the UI.
Can someone guide me if i need to install a cop file if so where can i locate it? Or a TAC case is the only way to do it?
Regards
Alok

with CUCM version 10.5.1.10000-7, u would be able to add only ISR 4431 and 4451.
with CUCM 10.5.2.10000-5, u would be able to add ISR 4321, 4331,4351 , 4431 and 4451.

Hi Manish,
Any idea if Cisco 4300 can still be supported with CUCM version 8.5?
Thanks,
Janice

Hi Janice,
Unfortunately I don't see its support on 8.5 and don't think it will ever be possible in the future

You should consider upgrading cucm to 8.6.

At the time of this writing TAC no longer seems interested in supporting 4300 (or 4400) series routers as MGCP gateways in CUCM 8.6.
I was referred to table 6 in the link below. You'll find support starts in 9.1.2.

Hi,
Is it possible to configuring router 4321 with the procotol H.323/SIP with CUCM 8.6 ?
Does anyone know something like that ?
This link table 6 give the information that the router 4321 just work with the version 9.1.2 and above.
Thanks,
