Most of the Telcos use their internet network to operate the SIP/VoIP part in transparent way. The landline (your phone) is connected to a modem and the modem does have the SIP account associated with your phone number, so when I call your phone number the switch (voice switch) will route the call to your SIP account and the modem will signal via the phone. So all the magic is under the service and the user can still use his/her phone. I don't have the time to google now good articles, but it is explained already at numerous places. There are still some ADSL/ISDN switches involved, but AFAIK the issue is they consume much more power and cost more (licenses and support) BR ____________________________________________________ tde-users mailing list -- users@xxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxx Web mail archive available at https://mail.trinitydesktop.org/mailman3/hyperkitty/list/users@xxxxxxxxxxxxxxxxxx
