In a multi site central call processing model of CUCM, would it be best practice to have hardware media termination points configured on all branch routers??
Up until recently, I've kind of had a hard time understanding what role they play. I understand that they seperate call legs etc etc, but I don't really get what they're actually used for or how they work in real life.
For example - tick the MTP box of a H323 gateway - don't know what that does Or if you're running a SIP trunk off the gateway router - you need to set up an MTP - don't know what that does.
To put it simply this is how I understand it - So if an MTP was configured on a branch router, if an external call into that branch is put on hold, the held call is terminated at the router. Without an MTP and depending on your MRGL's, is it moved to the MTP on the Call Manager server (ie through the WAN) until it's taken off hold?
