Capturing packets from Jabber client towards CUCM for tapping RTP streams do not require any sandbox accounts. Depending on where the Jabber client is installed (win/macOS), you can install wireshark on the system and start capturing upon reproducing the issue. This would capture packets only for to/from this node, likewise you can capture throughout the call flow at every node servers.
