[cisco-voip] FXS phone only rings one time!!!

[Kevin Thorngren]

Hi Paulo,

The problem might be that the inbound voip leg coming into router 1 is 
matching on the default dial-peer 0 and is failing to negotiate 
capabilities.  I would suggest that you create a voip dial peer on 
router 1 to receive the inbound portion of the call.  This way you can 
make sure the capabilities match if you make changes on router 2.

HTH,
Kevin
