Hi,
Just in case this will save someone else time, I was able to get my Vigor 2860, with firmware 3.8.9.4, sending sms messages using VoodooSMS by using the custom string below in the SMS/Mail Service Object, Custom 1 profile, Service Provider box.

https://www.voodoosms.com/vapi/server/sendSMS?
uid=###txtUser###&pass=###txtPwd###&dest=###txtDest###&orig=Firewall&msg=###txtMsg
###&validity=1&format=php

Please note that you may have to ask VoodooSMS support to switch on their Old API facility for you as their new API has key lengths that are too big to enter in the 2860 as it has a limit of 31 characters.

regards

Colin

Thanks for the information. I have something similar set up on a Vigor 2860 as well with VoodooSMS and I wasn't aware of the new SMS API being incompatible with it. That's useful to know if/when I set up any more routers with SMS
