Very SIP dependent. I believe both of these depend on large SIP
messages which tend to segment/fragment in the network. Firewalls and
inspection engines tend to choke on segmented/fragmented SIP. Try
disabling SIP inspecition/fixup along the path and check for
improvement. Otherwise, packet capture.<br>
