Question #: 103
Topic #: 1

A company is setting up B2B instant messaging capability using a secure client integrated into the on-premises Cisco communication platform. During the setup, the engineer discovers that external Usages from other businesses do not seem to reach the Cisco Expressway for instant messaging, but B2B calling seems to be working Internal chat between clients and chat toward clients is king m home offices using Mobile and Remote Access The engineer verified that the correct ports have been configured on the Cisco ASA, and the firewall rules on the expressway show no cation of any traffic What is the cause of the issue?

AThe XMPP service is not activated on the Cisco Expressway

BThe Cname record for XMPP is not configured or is misconfigured.

CThe SRV record for XMPP is not configured or is misconfigured.

DThe XMPP service is not running under services in Cisco IM and Presence Server

Show Suggested Answer

Suggested Answer: C

In Business-to-Business (B2B) instant messaging using Cisco Expressway, SRV records are crucial for external users to discover and connect to the correct XMPP service. The fact that B2B calling works but not instant messaging points towards a service discovery issue specific to XMPP.

SRV records for XMPP:Typically, the domain would have an SRV record like 'xmpp-client.[invalid URL removed]' pointing to the Expressway.

Wait, wait, wait... the XMPP service is like the DJ at the party, and if he's not there, the whole thing falls flat. Option A is the way to go, for sure.

I'd have to agree with Cecilia on this. The XMPP service not being activated is probably the reason we're seeing these connectivity problems. Gotta keep those services running, folks!

Let's check that and see if activating the XMPP service solves the problem.

Hmm, the XMPP service not running on the IM and Presence Server? That's an interesting one. Kinda sounds like the IT team left the XMPP party early.

I'm gonna go with option C on this one. If the SRV record for XMPP is misconfigured, that could definitely cause the issue with external clients not being able to connect.

The XMPP service not being activated on the Cisco Expressway seems like the most likely culprit here. That would definitely prevent external usages from reaching the platform.

B: That makes sense, it would explain why the external usages are not reaching the platform.
