Hey there RMN,
I assume that, if you’re seeing these errors in the log when you make a Call, that the 3CX functionality doesn’t work as expected?
Apologies, I haven’t used 3CX myself, so I’m not overly familiar with how it works
But, when you see these errors, what specifically is happening?
(Call not Made / not recorded in CRM / etc)
I’ve had a look for those error messages, and I’ve not found much:
This Github issue seems to refer to the same error messages, but isn’t regarding 3CX specifically.
It also seems to refer to slightly older versions of SuiteCRM:
https://github.com/salesagility/SuiteCRM/issues/6862
Which version of SuiteCRM are you on?
It might be worth upgrading if you’re on a version pre-7.11.18
There was also this forum post around the same error messages. Though, again, not related to 3CX:
https://community.suitecrm.com/t/custom-routes-file-is-not-exists-custom-application-ext-api-v8-config-routes-php/77621/2
There also seems to be a number of threads on 3CX’s forums regarding SuiteCRM, maybe some of them will be of assistance?:

https://www.3cx.com/community/threads/suitecrm-integration-has-anybody-done.79661/
It looks like 3CX also have a logging system:https://www.3cx.com/docs/3cx-log-viewer/
It might be worth having a look in there too, to see if anything of note appears
Let us know if you need any help, or how things go
