FXO offhooked.

Jump to solution

Good afternoon forum, i have the next issues with the NV7100:

1. FXO unhooked. I have 2 FXO connected to my 7100, i can make phone calls perfectrly, but i have a serious problem when i reciebe a phone call and it is not answered by an extention, because the line keeps in a offhook state. Does enny one has presented this problem?

2. Talking about both FXO lines, how can I make outgoing calls take one or another line? I have configured 2 trunk groups, but there is no difference, because the 7100 takes a line interchangeably

doesn't matter the prefix or the group.

Thankyou for reading, comments welcome!!

Thanks for providing that.  Both interfaces show Measured ERL:  0 dB. From these results it looks like there is an issue with the quality of the line.  I would recommend contacting the provider.

Thanks,
Matt

ing_gomez_clevermx,

For issue #1 have you tried running the ERL tool on the unit?  You can read detailed instructions on using the ERL tool in this guide: .  We always recommend running it on any analog line connected to the NetVanta 7100.  If running the ERL tool does not help (please try that first) can you post the results of the following show commands and debugs while recreating the issue:


debug interface fxo


debug voice verbose


show run interface fxo 0/1


show run interface fxo 0/2


show run voice trunk


show run voice grouped-trunk


For issue number 2, you can create two separate grouped trunks: one for each FXO interface.  You can then modify the accept template for both trunks to specify which numbers should get routed out each trunk.  Below is a very stripped down example that would send all inbound calls on either trunk to an auto-attendant at extension 8001, route all 7 digit outbound calls to trunk T01 connected to FXO 0/1, and route all 10 digit outbound calls to trunk T02 connected FXO 0/2.  If you want to route outbound calls based on what user is placing the call you can use .


!


voice trunk T01 type analog supervision loop-start


  caller-id


  trunk-number 8001


  connect fxo 0/1


  rtp delay-mode adaptive


  codec-group g711_first


!


!


voice trunk T02 type analog supervision loop-start


  caller-id


  trunk-number 8001


  connect fxo 0/2


  rtp delay-mode adaptive


  codec-group g711_first


!


!


voice grouped-trunk ANALOG_LOCAL


  trunk T01


  accept NXX-XXXX cost 0


!


!


voice grouped-trunk ANALOG_LONG_DISTANCE


  trunk T02


  accept NXX-NXX-XXXX cost 0


!




Thanks,

Matt

I ran the test, and I got 0 dB for all the impedances.

I will send you the debugs

If the ERL results came back as 0 dB there is a problem with the line.  Anything less than 10 dB is unacceptable.  Can you paste in the output of a show interface fxo 0/1 and show interface fxo 0/2 to confirm?

Thanks,

Matt

Transmit Gain: +0.0dB

Receive Gain: +0.0dB

I have to tell you, that we have to unplug the lines from the divice

because of the problem.
