> Hi,
> Im using asterisk as a VOIP<->PSTN gateway with E1 Trunk and SS7 signaling. When from voip is called emergency number (in europe it is 112) i have to pass it throu SS7 in following format:
> XXCYYY112
> Where:
> XX is a direction number (in US it will be number representing state)
> C - is hexadecimal "C" or 0xC
> YYY it is numer representing emergency office in "state"
> 112 is our emergency number
> EX: 15C100112 
> But libss7 does not allow to use 0xc. For now only 0-9 and 15 (#) are allowed. I Found in RFC3966 (5.1.3) information that in global traffic only 0-9 are allowed, but it is possible to encode additional characters. In accordance with E.164, these may not be included in global numbers.  Their meaning in local numbers is not defined here, but they are not prohibited. So to compile with polish regulations I addred support of 0xc. But i supose it might be good idea to add all 0xa - 0xd. I believe that 0xe might be encoded as asterisk, but i didn't found 100% sure comfirmation about this last theory.
> Below is patch for 0xc.
