res/res_pjsip.c: allow user=phone when number contain *#

if From number contain * or # asterisk will not add user=phone

Currently only number that uses AST_DIGIT_ANYNUM can have "user=phone" but the validation should use AST_DIGIT_ANY
this is a problem when you want to send call to ISUP
as they will disregard the From header and either replace From with anonymous or with p-asserted-identity
