VOIP support (ENUMER) already working, you can send ENUM lookup request to the public site:

$ dig -t naptr +short 08068886681.enum.enumer.org
100 10 "u" "E2U+sip" "!^(.*)$!sip:\\1@tollfree.alcazarnetworks.com!" .

Or directly to your wallet (if you locally keep EMCDNS gateway):

$ dig -t naptr +short 08068886681.enum
100 10 "u" "E2U+sip" "!^(.*)$!sip:\\1@tollfree.alcazarnetworks.com!" .

to activate ENUM option in the wallet, use config params in the emercoin.conf:

#emcdnsallowed=.coin|.emc|.lib|.bazar   # remove Allowed TLDs without ENUM
emcdnsallowed=$enum|.coin|.emc|.lib|.bazar      # add Allowed TLDs with ENUM

enumtrust=ver:enum
enumtollfree=@enum:tollfree

Example of the ENUM record you can get from EMC NVS with the command:
name_show enum:12027139373:0
