i am having 2851 ccme and i am having 7 analog lines and one 30 channel PRI line
what i need is once the analog lines are used (full ) then automatically system has to select pri line to call outside
and i am using 9 to dial out.
i attaching my config in this
in my config there is two access one is 9(for analog line ) and 0 (for pri line) and some direct numbers are there in PRI line.
You can use a trunk group with preference labels to create an ordered list of interfaces to use for the outbound calls. Each of the analog voice ports would be 1-9 and the PRI would be preference 10.
can you explain me with my config it is very helpful to me becuse i tried it , but i am getting confused.
