FXO incoming call diverted to "always off-hook" FXO/FXS/E&M port

Unanswered Question
Mar 9th, 2009

I am trying to find out if its possible to divert an incoming PSTN call through an FXO (origination) port to a FXO/FXS/E&M (destination) port (on the same router) which is always open or off-hook . The incoming call can be automatically answered without picking up the phone handset (which is connected to the destination FXO/FXS/E&M port).

Something like this -

PSTN ---> FXO ---> FXO/FXS/E&M (always off-hook) ---> phone set

I have tried the config below but it requires someone to answer (off-hook) the phone when it rings.

voice-port 1/0/0 (FXO port with PSTN line)

connection plar 100

dial-peer voice 100 pots

destination-pattern 1..

port 1/1/0 (E&M port with PBX phone line)

Thanks very much.

Try using the 'connection trunk ' command with dial peers that point numbers to both sides.

So you could have something like this:

voice-port 0/0/0

connection trunk 1001

voice-port 0/0/1

connection trunk 1002

dial-peer voice 1 pots

destination-pattern 1001

port 0/0/1

dial-peer voice 2 pots

destination-pattern 1002

port 0/0/0

hth,

Follow your config. I have a question. Do i need to configure a dial-peer voice voip because the 'show voice port summary' shows the connection trunk is not operating.

# show voice port summary

PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC

====== == ========== ===== ==== ======== ======== ==

1/0/0 -- fxo-ls up dorm trunked trunked n

1/0/1 -- fxo-ls up dorm trunked trunked n

I have put in a dial-peer voice voip in the config. This time the connection trunk is operating.

# show voice port summary

PORT CH SIG-TYPE ADMIN OPER STATUS STATUS EC

====== == ========== ===== ==== ======== ======== ==

1/0/0 -- fxo-ls up up trunked trunked n

1/0/1 -- fxo-ls up up trunked trunked n

The problem now is when I call the PSTN line connected to FXO port 1/0/0, it is always engaged. What should I do?
