ATA 190 Troubleshooting
Explanation
In Cisco Unified Communications Manager, you can configure the
network to use the G.729 protocol (the default is G.711). When
using G.729, calls between a phone and a mobile phone will have
poor voice quality. Use G.729 only when absolutely necessary.
A prolonged Layer 2 broadcast storm (lasting several minutes) on
the voice VLAN may cause phones to reset, lose an active call, or
be unable to initiate or answer a call. Phones may not come up until
a broadcast storm ends.
