static int ss7_parse_prefix(struct dahdi_pvt *p, const char *number, char
*nai)

if (strncmp(number, p->ss7->internationalprefix,
strlen(p->ss7->internationalprefix)) == 0) {

} else if (strncmp(number, p->ss7->nationalprefix,

} else if (strncmp(number, p->ss7->networkroutedprefix,
strlen(p->ss7->networkroutedprefix)) == 0) {
strip = strlen(p->ss7->networkroutedprefix);
*nai = SS7_NAI_NETWORKROUTED;
} else if (strncmp(number, p->ss7->unknownprefix,
strlen(p->ss7->unknownprefix)) == 0) {
strip = strlen(p->ss7->unknownprefix);
*nai = SS7_NAI_UNKNOWN;
} else if (strncmp(number, p->ss7->subscriberprefix,
strlen(p->ss7->subscriberprefix)) == 0) {
strip = strlen(p->ss7->subscriberprefix);
*nai = SS7_NAI_SUBSCRIBER;
} else
*nai = SS7_NAI_SUBSCRIBER;
return strip;
}
network routed is matched before subscriber - set
"ss7_networkroutedprefix=NA", so it wont match on blank
