Implementing Cisco IP Telephony and Video Part 2 (CIPTV2, legacy) — Question 44

You have deployed a Cisco 2821 ISR to perform as an SRST voice gateway at a remote site. During a network failure between the remote site and the central office, some of the phones located at the remote site are unable to make phone calls. Which two options are potential causes of the problem? (Choose two.)

Answer options

• A. The ccm-manager fallback-mgcp command is configured incorrectly on the voice gateway.
• B. The site has exceeded the number of SRST endpoints supported by the voice gateway.
• C. Some phones at the remote site are assigned to a device pool without SRST reference.
• D. The site has exceeded the number of simultaneous calls allowed in SRST mode.
• E. The ccm-manager fallback command is configured incorrectly on the voice gateway.

Correct answer: B, D

Explanation

Option B is correct because exceeding the number of supported SRST endpoints will prevent some phones from making calls. Option D is also correct as exceeding the allowed simultaneous calls in SRST mode can lead to call failures. The other options do not directly relate to the symptoms described in the scenario.
