Hello, i need to send (and receive) via an ITU ss7 link a number starting with the letter E, but Asterisk is sending it as 0 and when receiving similar number sent from our provider i get no number at all and the call fails on the s extension. In chan_dahdi.conf there is: ; pridialplan may be also set at dialtime, by prefixing the dialled number with ; one of the following letters: ; U - Unknown ; I - International ; N - National ; L - Local (Net Specific) ; S - Subscriber ; V - Abbreviated ; R - Reserved (should probably never be used but is included for completeness) but does not work at all for ss7 and even the N prefix (for national) is sent as 0 according to ss7 debug. where in the code should i look about changing this behavior?
