Cisco 4331 with NIM-4FXSP and CUCM 10.5.2

[Clifford McGlamry]

According to the documentation I can find, the NIM-4FXSP is supported under CUCM 10.5.2.  However, it doesn't appear as an option for cards when we look in the system in setting up a 4331 (there is a NIM-4FXS).  What device pack is required to get the NIM-4FXSP to appear?  I've been through a tone of the release notes on device packs, google,etc., and am not finding any mention of it.

Hi,

According to that guide https://www.cisco.com/c/en/us/products/collateral/routers/4000-series-integrated-services-routers-isr/datasheet-c78-733646.pdf there is not difference between FXSP and FXS.

And are you sure, that the 4331 router is supported by 10.5.2? The router model is a new model, CUCM 10.5 is end of everything since years.

It's certainly configurable, so I would assume it's supported (the docs I've seen say it is).  Customer is planning to upgrade, but they haven't done so yet.  Like a lot of customers, they are not very happy with Cisco's new licensing model where they have to rent, and never own, their licenses. But that's a whole different discussion.

Yes, it is supported according to that https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/10_5_1/CUCM_BK_CE15D2A0_00_cucm-release-notes-1051/CUCM_BK_CE15D2A0_00_cucm-release-notes-1051_chapter_01.html#CUCM_RF_C712875E_00

And yes, heard the discussions many times too, it is what it is

Are you trying to register those ports as MGCP devices? If you have the ISR configured as a SIP gateway with dial peers pointing to CUCM, that would certainly work.

While that would work, we're just trying to replace a device here.  Not going to try and re engineer stuff unti they get the upgrade to the UC servers done.
