Hi guys
Can somebody help us?
We have
100x 9951 (sip)
400x 69xx (sccp)
UCM 9.1.2
The 9951 sip are flapping between UCM. We idenfied timeout between phones/ucm.
After sniffer the network, we identified big number retransmission of packets (from sip phones) and a big number of FCS error.
IN sccp, we dont received error, so we migrate 1 phone sccp to sip and the result.....also problem, a big number of fcs and restransmission
