What's the reason to assign empty value before config processing?
If the tag has value then will be ast_strdup()/ast_free()/ast_strdup().
If assign empty value after config processing at sip_endpoint_apply_handler()
then will be only one ast_strdup() in any cases.

The next functions leak memory on multi options:
caller_id_handler
caller_id_tag_handler
voicemail_extension_handler
contact_user_handler
