I have implemented voice-port cable-detect on my VG350 (15.3(2)T) with SM-D-72FXS modules and MGCP signalling loop start. The documentation is not specific as to what is defines "connected" and "not connected" state and I have a functioning phone that shows "not connected" state.
The VG350 performs cable-detection by using low-voltage REN measurement. This means the FXS port will inject a low ring voltage into the line and measure the impedance. If the impedance is low (means there is a ring circuit) the assumption is that there is a phone plugged in.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
