Yes, that's the so-called emergency number. Unfortunately, the sheer number of 'emergencies' at the moment is probably rather overwhelming them.
And all the mention of people being on hold for ages and getting cut off. 6 times out of 10 that is your telecoms provider hanging up your call as no 'activity' has been detected and assumes you've left your phone off the hook after making a call. Always a good move to send a 'keep alive' signal every ten minutes or so, just by pressing any button on your phone to generate a DMTF tone. That will prevent your outgoing call being abruptly terminated. The other 4 out of 10 disconnects are down to the party being called, however. Some kind of 'callback' needs to be implemented so that the call centre operator doesn't just shrug their shoulders and move on to the next call in the queue.
