What are your agents/supervisors using for browsers? Anthony Holloway was the first to uncover that if the browsers lack WebSocket support they will fallback to a polling mechanism that pegs the CPU even at relatively low scale. It effectively creates a DDOS condition.

I would use the Call Consult Transfer step since it gives you supervision. You would just need to code the persistence into your script: if they didn’t answer, try again or try the backup number. The other thing to consider here is what you are going to do if voicemail answers instead of the human. Call Consult Transfer has a timeout parameter that you can use to prevent CFNA but that doesn’t catch CFB (eg the cel phone is off/out of coverage area). CCX doesn’t have a native solution for that because you can’t play an IVR (eg “press one to accept the call”) before completing a transfer. You also can’t bridge/merge two Contacts together. Unless you can disable VM for the on-call destinations, you may have to look at other options to get explicit confirmation/acceptance. One complicated way to do that would be a CUCM DN with SNR configured using the User Control setting for the SNR Voicemail Policy on the Remote Destination. If that DN otherwise had no call forwarding it would return reorder to CCX if the RD didn’t press a digit to accept the call. The gotcha to this is you probably want a dedicated on-call phone instead of a user’s normal cell number because any calls from that number to CUCM will have their caller ID masked as if they’re coming from the DN with SNR configured.

DNS is a mandatory component of all Jabber deployments. Many features (e.g. Service Discovery and basic TLS certificate validation) depend on it. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/12_5/Planning_Guide/cjab_b_planning-guide-for-cisco-jabber-125/cjab_b_planning-guide-for-cisco-jabber-125_chapter_010.html?bookSearch=true#id_83190

If you’re preference is to keep this config within CUCM, I believe you need a CALLED Party Transformation Pattern. Alternatively, you could perform this on CUBE with a voice translation rule/profile. https://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/64020-number-voice-translation-profiles.html

Try with a forward slash instead. You’re on GNU/Linux after all. The only reason backslash works at all is because Cisco tried to write parsing logic that catches and replaces it to make upgrading off of Windows easier. Perhaps that isn’t working when you bury the backslash inside a variable?

Faxes will never succeed with G.729, full stop. Annex B (ie VAD) would only make that situation worse. You need to use either G.711 for fax passthrough or T.38 fax relay, the latter of which is strongly preferred.
Your post is missing a lot of relevant details (eg config of both the VG and CUBE, what the PSTN circuit is and in the case of SIP what the provider supports, etc) so it’s difficult to provide specific guidance here. Here’s a common config reference to get you started:

You could also write your own XML SDK phone service to substitute the login/logout URL native to CUCM. By taking control of the actual EM login/logout via the EM API you could coordinate other API calls along side it, such as an AXL call to toggle off SNR for that user. Cisco DevNet would have documentation on all of the APIs but if you’re not comfortable (or have the time) developing your own solution, it may make sense to engage a Cisco partner who writes custom integrations as part of their core competency.

It does not. I have seen customers use an 8851 or 8861 with a USB-attached speakerphone though. The phone sees it as a headset (I suggest disabling the native phone speakerphone to help users). The Jabra Speak 810 is probably the best example: https://www.jabra.com/business/speakerphones/jabra-speak-series/jabra-speak-810

Can we first pause and consider both why the call needs to be transferred to a CUC Call Handler for IVR treatment - which increases CTI activity from a CCX scaling perspective - and why you desire a new session ID? My initial reaction is to say neither of those things are a desirable design. To answer your question though, I believe a CUCM Translation Pattern from CUC back to CCX before the Trigger would break session ID persistence. This is dangerous though if you’re not careful. Namely it must not be the same extension as the CCX Trigger itself and CCX must never transfer/redirect to the TP directly, only CUC can. You are flirting with a memory leak by doing this and going against the intended design of CCX.

Which record are you asking about?
The _sip records are an option for implementing resiliency/failover to the SIP PUBLISH trunk from CUCM. In the past they were also used when leveraging CUPS (now IM&P) as a SIP Proxy, such as with UCCE. That reference design has moved to CUSP though.
The _xmpp-client and _xmpp-server are useful for 3rd-party / standards compliant XMPP clients or servers, respectively. For example, _xmpp-server must exist on the public DNS zone, pointed at Expressway-E for inter-domain federation.

You will need to query an external service that is capable of answering that question. If I may suggest, dropping the call outright if you guess wrong is a crappy programming choice on your provider’s part. The most modern approach is a RESTful API Call, for which CCX is a handy step in modern versions.
There are multiple services for querying whether a number is mobile or not (eg https://www.twilio.com/lookup); however, I’m not sure that will be good enough if the risk of an error is a dropped call. For example, what if the user has a basic cellphone without a smartphone OS? That would be flagged as mobile.

Kudos on making it this far! Mixed mode and CAPF can be intimidating to learn.
CUCM 12.5 introduces a new Online CA mode for CAPF that should do exactly what you’re asking. It turns CAPF into a relay to ADCS instead of CA of it’s own. The phone’s CSR will be forwarded to the ADCS CA to be signed using the specified certificates template.
https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/12_5_1/cucm_b_release-notes-cucm-imp-1251/cucm_b_release-notes-cucm-imp-1251_chapter_010.html#reference_BAC0DDC63B8795D884C3D8D1400C90A4
https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/security/12_5_1/cucm_b_security-guide-1251/cucm_b_security-guide-1251_chapter_011110.html#task_33FB14EFB706D2989EAB3654A1618754
One word of caution: be careful to get the Key Usage and Extended Key Usages correct as well as validating that all URLs (eg AIA, CRL, OCSP) added by the CA are in HTTP URI format. This is not the default for ADCS and is often overlooked when setting it up. The Microsoft Press book Windows Server 2008 PKI and Certificate Security is still a great reference.
https://www.microsoftpressstore.com/store/windows-server-2008-pki-and-certificate-security-9780735640788
PS- CUCM 12.5 also introduces SIP OAuth support, currently only supported by Jabber and MRA-connected phones. I would highly suggest using OAuth for Jabber instead of CAPF since it eliminates the Windows credential roaming challenges you will have with LSCs. While OAuth tokens will likely come to IP Phones in the future - my assumption only, not a statement about Cisco’s roadmap - they are not expected to solve the 802.1x use case you appear to be exploring.
