I am working on Cvoice exam and I am having some difficulty with getting
vofr to work.
I have 2 x 2621 running IOS 12.07 T with NM2V and VIC-2FXS, & Wic1T
linked together either via serial port or via ethernet.
Routers R1W1 and R2W2.
I can make local calls from one FXS port to another port ok.
I can also make VoIP calls over ethernet from a FXS port on R1W1 to FXS
port on R2W2 ok.
I can also make VoIP calls across Frame Relay cloud. dlc 32 carrying
NLPID encapsulated IP ok.
When I try to make Vofr calls across Frame Relay cloud, dlc 16. I get
nothing!
LMI is fine, and up (lmi-type ansi)
debug frame-relay packet
shows dlc 32 active when I make VoIP calls with NLPID encapsulation
but there are no frames sent / received for Vofr. The phone gives
nu tones.
Does any one have a working vofr config or know of a problem with vofr?
Many thanks
Peter
