It looks like 32 - national city prefix and C120 - routing number (but I’m not sure)
It is used to redirect 112 call to specified city.
I have several numbers with C letter police / ambulance / fire station
I call 112 but I MUST add 32C120 to my outgoing rute via sip trunk to achieve local emergency call.
Don’t You read what I wrote ???
I have to PREPEND a prefix to 112 number on phone i press 1 1 2 but via trunk it is send 32c120112
There is no other way to send it.
I don’t have posibility to use other analog line or sth.
Yes I read what you said!! That is why I asked those questions DTMF A-D are legitimate codes it’s just that few phones can dial them usually just the SS7 inter-carriers so they are not appropriate for SIP, nonetheless . . .
You will could write a “pre-dial hook” to mangle your dialing depending on which city your various phones are in to suit your carriers peculiarities, but you are indeed you are in a very small minority, so few will get excited about your problem.
And there U will find number tables in wich you can see my problem.
each city has it’s own Emergency center and when I dial 112 my asterisk must send
WSN d. 32 wyróżnik HEX C IDL AUS AL 170 NR AUS AL 112 all these thing give us 32C170112
and after that my 112 call is being directed to choosen Emergency center.
I live in Silesia so my nearest Emergency Center is in Katowice so 32C170112 but a person who is living in Warsaw will use 22C700112 for the nearest Emergency Center in Warsaw.
So, perhaps do as two people have now suggested, write your custom hook to mangle your outbound calls no??? . The “mangle” will have to handle all of your extensions in any city you provide service in to suit the prevaricates of your provider and apparently the requirements of your " art. 20 paragraph. 1 of the Act of 22 November 2013"
(As you can see, I have read your link !!! , but I am pretty sure no-one here has a “C” key on their phone so if that is how it works in Poland, and you care not to take US help, then you will need to find Polish help.)
You didn’t understand me … we dial 112 but my asterisk has to put 32C170 in front of 112 dialed by the phone in my city area.
End user don’t know anything about 32C170 he just dial 112
I had to put on asterisk in 2 days from zero to working envoirnment so I’ve added it via MySQL database and it worked in outgoing route.
And now when I have working asterisk I can work on it and correct my errors (don’t ask me why in this way )
And don’t get annoyed about my previous posts
For now I have sth like this.
So I will have to write custom hook on it and then I will have to add my extensions to use this hook ???
I DO understand you, and you have found a workaround, so either patch the FreePBX code to allow A-D as well as 0-9 on that page or don’t rely on the GUI to honor any changes. You could submit a feature request to FreePBX.
One problem being that you will need to route each extension to a different route depending on it’s physical location, a custom hook could do that automatically by looking at the area code of the CallerID of the extension and looking up the appropriate prefix.
