i have Cisco Unified Communication Manager 7.0 with Cisco 7816 Server in Egypt Cairo
and router 2811 with cisco callmanager express software at Algeria
the question is,in case i configured the 2811 router as SRST do the ip phones at Algeria register directly to ccm7.0 at Egypt Cairo over the WAN. and what is the round time delay that is accepted for quarntee the voice quality over the WAN.
i have pinged the 2811 router from cairo and time is over 500ms
