I have a phone connected to 2-port FXS card on ISR 2821 router.this router is registered to CCM 6.0.I selected SCCP while adding this voice router to the CCM.
The problem is there is no dial-tone on the analogue phone connected to fxs port.Hence we can't make outgoing calls from analogue phone to otherIP Phones reg on ccm.But strangely incoming call to this phone from other IP phones reg to call mgr works fine.
The analogue phone is properly registered in the CCM.
Attached is the configuration of the ISR router.
Can somebody suggest if something is to be more configured on 2811 or in the CCM.
atatched is the ISR router config.
If necessary please suggest appropriate URL to look into.
