Fix the DailIn conferance # tel link is broken for some phones
These links are currently broken for some types of phones.
Doesn't work on my Samsung Note 8 phone but works for IPhones.
The link current format is 'tel:+1 555-555-5555,,12345678#'
The space is an absolute NO in tel links.
The dashes should be ok, but does not help and breaks on my phone. Since its a link those dashes can/should be omitted as well. The less 'junk' in the url the less chance of breaking stuff
