Log says possible config issue as cucm is rejecting the registration with reason code 24.
Please can you disable any add on modules if any and make sure correct config is assigned for the phone model.

Can you attach the phone console logs?
You can change the CM detectin failure in phone config from "normal "to "delayed" it you want the phone to wait more before keepalive failure.
Also check if correct phone button template is applied and disable is any expansion module is added to test.

Building direct trunk from CUCM to provider might not be a good idea as provider will have access to the inside network subnet where your CUCM is residing.
Just enable below and add bind commnds to make it work as SIP and set dial-peer to provider .
voice service voip
allow connections sip to sip
SIP
bind control source-interface GigabitEthernetX/X bind media source-interface GigabitEthernetX/X.
You can also have bind command specific to the dial-peers so that WAN interface is used for provider side and LAN interface is used for cucm side .

If you are asking specific to software MTP's , it will not utilize the any DSP resources however you will have to size them as per CPU limitation , I think you will get the info if you look around little( refer below link) .
https://supportforums.cisco.com/discussion/11948661/how-many-software-mtp-sessions-isr-g2-router-can-support
On ISR G2 i have seen 400-500 resources with very minimal or no impact on CPU.
For rest DSP resources, you can use calculator.

Two things i know about hardware MTP's.
Hardware MTP's will be used where you need transrating , in case p time mismatch between two ends .If one side uses 20 ms and other is on 10 ms pactatization .Most likely the cases where you have third party vendor or SP which doesn't support 20 ms.
Also Hardware MTP will utilize your DSP resources so if you have enough of them you can configure HW otherwise go with SW as you can configure more session based on the hardware specs.

You may not need a CUBE to get it working and SIP gateway should just work fine .However if you have CUBE licenses enabled it will enable more features.
You can set it up redundant pair with stateless fail over with call preservation ,also latest IOS version has many features like more flexibility when you are doing SIP header modifications on CUBE.
Destination server group - You can have multiple destination under single outbound dial-peer
Multiple incoming patterns under same dial-peer or you can also use a text file this way you don't need multiple dial-peers.
You can use 2921 as cube( paper based license no need to install any file etc ) however based on it CPU and memory it will support max 200-400 active sessions .So you may want to check on the utilization before you plan on using 2921.

If you are using more licenses then what is available on ELM/PLM then it should have gone into grace period of 60 days ,i believe system shouldn't be impacted during this time.
You can check what last compliance time was as per below screenshot and see if actually you have been in violation status for long time.
Only if the license status goes to expire from compliance only then it will stop working.
You can check licenses status inside system settings-licenses. Also RTMT alert can be set as pointed below by Rob , which triggers an alert if you exceed the license usage from available pool.

There shouldn't be any problem for certificates unless cluster are in mixed mode .

Yes, no license file to install but you do need a paper based licenses from cisco to increase the number of sessions.So you need to raise a PO for paper based licenses for your CUBE .thanks

You can try this TAC tool link and test the SIP profile.
https://cway.cisco.com/tools/SipProfileTest/
Using below SIP profile for PAI , i could modify the anonymous to the main number as you can see.

You might want to check eventviewer/application logs PG2A to see if there was a spike in the CPU , memory etc.I have seen OS level issues causing MDS sync to be broken apart from regular network issues.if memory serves we had to upgrade the PG.
May be run a ping plotter between two sides to detect network failure as sometimes network team might not be able to detect a small blip which we can see in ping plotter .

You will need to get paper based license for 25 sessions from cisco because CUBE uses honor based licenses. So you will not find any separate license file , rather it runs on paper based licenses once you install UCK9.

Hi Vijay,
You may need to add all the CUCM nodes on gateway trust list , gateway may be rejecting the call due due to Toll fraud prevention.
or you can do no ip address trusted authenticate to allow all ip addresses .

I do not think there is an error on CME side ,we should atleast see the call hitting CME.
Please check failed call logs from Avaya end and check network routing in both directions.
