[cisco-voip] problems on Analog phones connected to vg224

[Jefflin Choi]

Hello all,

Users are having problem on analog phones connected to VG224 port and
registered at CCM 5 .

Topology:
analog phone ----VG224
                             |
                             ---------callmanager 3845(FXO) outgoing and
E1R2 for incomming call.
                             |
                             ---------3845(with FXO for outgoing and E1R2
DID for incomming call).

Problems:
1>analog phone A calling Analog Phone B. If phone A hangs up after the call,
Phone B gets disconnected with "your phone can't be completed as dialed".

2>When phone is off hook then user dials, and puts the phone on hook, it
takes some time to wait before dial tone appears again.

3>There is a fax machine that needs to forward calls using hookflash.
configured CCM 5  with 2 maximum lines but when hookflash pressed, nothing
happens....after 3-4 press of flash button call on the called party gets
disconnected.

4> Users doing phone banking system is having failure entering his/her pin
on the analog phone. Is the dtmf-relay needed to be configured on FXO port?
can't seem to find the command on the pots dialer peer.

Is there any fine tuning parameters that i could use to solve the above
problems? These analog phones are connected to a nortel pbx system before
without any problems and i got to prove that it works on cisco devices as
well.

Thanks in advance!

Cheers,
Jeff
