I'm hoping someone can help me wrap my head around this. Nothing is broken, I'm just trying to get a better understanding of how dial peers and voice ports work. I've been reading the white papers provided by cisco, and I end just end up more confused.
Below is my working config of a voice T1 between two routers. I've cleaned it up a little bit to get rid of any lines that don't pertain to my confusion ( fax pass through commands, g711 commands, etc).
The attached JPG shows exactly what I'm trying to do. In the JPG, I'm trying to figure out what has to match up with what in order for this to work. I'm just dealing with the signaling channel. Once I understand the signaling, the voice bearers will follow the same logic. As you can see, the number 11300 shows up three different times on one side and three times on the other. Are any of these just arbitrary labels that someone happened to name 11300 for consistency's sake? Again, I think the JPG will explain exactly what I'm trying to figure out. Thanks in advance.
