Question 1 of 30
A company is experiencing intermittent call drops in their Cisco Unified Communications Manager (CUCM) environment. The network team has confirmed that the bandwidth is sufficient and that Quality of Service (QoS) is properly configured. However, users report that calls drop after a specific duration, typically around 30 seconds. What could be the most likely cause of this issue, and how should it be addressed?
SIP session timers are misconfigured, leading to premature call termination.
The network firewall is blocking RTP packets after a certain timeout.
The CUCM server is overloaded, causing delays in call processing.
The endpoints are using outdated firmware that does not support the latest codecs.
