VVX400 100% CPU Utilization


VVX400 100% CPU Utilization



We have a customer that has VVX400's running They are utilizing 10-12 of the lines as registered extensions to a single SIP server. They are complainig that their phones are acting very slow and with CPU reaching 100% at those times. This usually happens during busy hours when multiple lines are ringing at the same time. They want to keep the lines on their phones for outgoing caller id purposes. If these phones were designed to handle 12 registered lines why is the CPU spiking causing the phones lag and become basically unusable. Any recommendations would be helpful.  i have attached pictures of the CPU spikes on multiple different phones.
