FXO off-hook forever; IP Phone keeps ringing.

Unanswered Question

Hi, I am using CCM4.2 and 2811 as GW, I configured the FXO ports and assigned DN's respectively. When I tried to call from outside, it is forwarded to the assigned DN and rings, but the IP phone keeps on ringing even if i hanged-up, I checked the voice port status and it is stuck on off-hook. Each voice port has the following commands:



Please help!

I have this problem too.

Did you try shut /no shut the voice port? or

resetting the phone?

Does this happen to all of your lines coming into the FXO card, or just one? I recently (last week) had a batch of FXO cards that were bad (5 cards total). The ports on the card would work fine for a day or so, and then fail (causing incoming calls to ring forever). If you check the output of 'debug vpm signal' it may help to narrow the cause.

u have solved your problem?if so how ?

because i have similiar problem

i got ccm 4.1.3 and fxo ports connected fct's for gsm connections

Gateway and CCM has mgcp connection.

on callmanager fxo port configuration I configured Attendant DN for incoming calls .

what is the relation of using battery reversal command for directing the incoming calls to Attendant DN which is specifed on callmanager.

Because if i use battery reversal under fxo port , calls routed to Attendant DN but only one time phone rings and then disconnects.

But if i use no battery-reversal command under fxo ports calls go to the AttendantDN and call can be set up succeessfully.

any idea
