Are you on SIP, ISDN or analogue lines?

 

[JamesNav]

ISDN but it is also on internal calls!

Make sure your system ip address range and your ip phones/mfim are on the same subnet.
For example if your mfim has an ip address of 192.168.x.x and well as your ip phones but the system ip address range is 10.10.10.1 to 10.10.10.50 then you need to change the system ip address range to match the 192.168.x.x ip range that your sets and mfim are on.

they are all on matching ip ranges.

Are they using a POE switch? If so, are you bottle necking the max power output?

Are the phones using the dual lan? Could well be QoS?

Is it all ip phones or just the usual suspects? If its random i would spread the load on your switches and if possible, just for testing and for an hour or so, split the phones from the data.

Are your slts on the ipecs50 or via an sltm?

What version ipecs you running? What version phone software you got on too?
