| The number 999 is a lifeline for those in distress. Probably every adult knows its purpose and, when faced with an emergency, even toddlers have been able to dial these crucial three digits. | The number 999 is a lifeline for those in distress.

| BT receives 30 million emergency calls a year - either to 999 or 112, the European emergency services number, which works in all European Union countries.

| But several million calls a year do not follow this pattern, and the emergency number is dialled but no-one actually speaks to make a request.

| The code of practice says in the "overwhelming majority of cases" these calls are customer misdials, such as a phone keypad activated in a bag or pocket, or even children playing. But it acknowledges "there is always a possibility of it being a genuine caller who cannot speak". It also says "very large numbers" of accidental 999/112 calls are received from mobile phones. | The code of practice says in the "overwhelming majority of cases" these calls are customer misdials, such as a phone keypad activated in a bag or pocket, or even children playing.

| In 2001 the Metropolitan Police introduced a country-wide system called Silent Solutions for dealing with the growing number of silent accidental 999 calls. When a call is made, operators from police forces around the UK attempt to obtain a response by asking a series of questions. | In 2001 the Metropolitan Police introduced a country-wide system called Silent Solutions for dealing with the growing number of silent accidental 999 calls.

| Yet Hannah's tragic case is not a one-off. In 2005 Farah Noor Adams was raped and murdered in Glasgow. She had made a number of silent calls when she spotted she was being stalked by her eventual killer. But they too were cut off by operators when she failed to respond. | Yet Hannah's tragic case is not a one-off. In 2005 Farah Noor Adams was raped and murdered in Glasgow.

| But there are occasions where silent calls do work. One woman who was attacked at her home in Kensington, London, managed to make a silent 999 call. This led to the police tracing her call and visiting her home, where they captured her assailant. He was eventually convicted in 1991 of rape, possession of a firearm and attempted murder. | But there are occasions where silent calls do work.

| And emergency services in some parts of the country now respond to texts sent to 80999. This allows messages to be sent directly to the police control room.

| I appreciate that it's difficult to screen accidental 999 calls, but why is the practice of dialling 80999 not nationwide already? I too am a mum to a beautiful, caring 17-year-old daughter. I constantly nag her to carry her mobile for her own safety and keep it charged and in credit. Please bring in the National Emergency Text number as soon as possible.Deb, Rainham, Kent | I appreciate that it's difficult to screen accidental 999 calls, but why is the practice of dialling 80999 not nationwide already?

| I understand the problems of trying to weed out the very few genuine calls from the many accidental calls. However, in Farah's case, she made a number of silent calls to try and get help. Couldn't a computer system monitor the number of silent calls and if several are made in succession from the same number, police could investigate? These could still be accidental but it would be less likely.Helen, Durham | I understand the problems of trying to weed out the very few genuine calls from the many accidental calls.

| I worked taking 999 calls for two years in Glasgow. When I read about the hoax calls made by international celebrities, my first thought was "what an example". The emergency services have enough to deal with without celebrities turning the hoax call into a national pastime. The more calls dealt with by the emergency services, the more difficult it is to pinpoint "THE" call. I can only say the dedication and effort made by these call centres to ensure valid calls are answered is exceptional and needs more exposure.

| Why not just have a separate number that means "I'm in trouble but cannot speak?" Surely the cost of creating and routing another number, and flagging the difference to an operator on screen would be a tiny percentage of the annual budget for running the emergency services.Will Shaw, Barnsley | Why not just have a separate number that means "I'm in trouble but cannot speak?"

| What you don't mention is what to do in a situation where there is an emergency and the person can't talk or even obviously use the phone. Dial 999 wait three seconds then press 55?

| The emergency services cannot afford to take the chance that help is not really needed. Because of this the Royal Canadian Mounted Police has a policy of a mandatory response to any incomplete call or interrupted one, to a police control room. That one dialling may be the only chance a victim of crime or life-threatening situation has to desperately call for help. Not checking it out is a NON OPTION, in my experience and opinion...

| I'm disgusted. I was taught at school, by visiting police, that a silent 999 call would be treated as a police matter and they would be dispatched immediately. This has changed but would anyone in that situation be aware of this? The 999 service is not something to be treated with the same disdain as commercial operators treat their customer support services, and yet this "55" trick seems to come straight from the same hymn book. Basically, it's cheaper. I'm guessing the silent call that worked (back in 1991) was before they introduced this Silent Solutions nonsense. Still, with about 100,000 silent 999 calls per day, a better solution is not clear. Eddie, Oswestry | I'm disgusted.

| I am not at all surprised at the number of silent calls, since even locked keypads still allow 999 emergency dialling - this is deliberately DESIGNED IN to mobile phones. So even phones with locked keypads may dial emergency services if buttons are accidentally pressed - eg in a pocket.Draigalban, Edinburgh, Scotland | I am not at all surprised at the number of silent calls, since even locked keypads still allow 999 emergency dialling - this is deliberately DESIGNED IN to mobile phones.

| As it appears that the majority of these calls are from mobile phones, I suggest the following to either eradicate the cause, or prevent the call from going through or being cancelled once activated. Somewhere on the mobile a lock button can be fitted that can only be released by an emergency service officer. The button is pressed and the emergency number dialled. The button is released. That number will now remain open so it can be traced. The line will remain operative until the call is cancelled by an official in attendance. Effectively it cannot be disconnected by anyone else. If an operator tries to disconnect, the emergency number will repeat call. This should dramatically reduce the number of accidental calls - it may even save a life.Tony Ive, Petersfield, UK | As it appears that the majority of these calls are from mobile phones, I suggest the following to either eradicate the cause, or prevent the call from going through or being cancelled once activated.

| If you are trying to make a surreptitious emergency call, it is unlikely that you will be able to confirm your situation. Couldn't mobiles have a panic button with a suitable cover?

| I had always hoped if I needed it, I could do what Hannah did. In fact my previous handset had an option to call 999 automatically if you played with a fixed pattern of buttons in your pocket.
