Hi
TEL URI does not have the "user=param" syntax.
Please refer section 3 of RFC 3966 for the tel URI syntax.
The "tel" URI has the following syntax:
telephone-uri = "tel:" telephone-subscriber
telephone-subscriber = global-number / local-number
global-number = global-number-digits *par
local-number = local-number-digits *par context *par
par = parameter / extension / isdn-subaddress
isdn-subaddress = ";isub=" 1*uric
extension = ";ext=" 1*phonedigit
context = ";phone-context=" descriptor
descriptor = domainname / global-number-digits
global-number-digits = "+" *phonedigit DIGIT *phonedigit
local-number-digits =
*phonedigit-hex (HEXDIG / "*" / "#")*phonedigit-hex
domainname = *( domainlabel "." ) toplabel [ "." ]
domainlabel = alphanum
/ alphanum *( alphanum / "-" ) alphanum
toplabel = ALPHA / ALPHA *( alphanum / "-" ) alphanum
parameter = ";" pname ["=" pvalue ]
pname = 1*( alphanum / "-" )
pvalue = 1*paramchar
paramchar = param-unreserved / unreserved / pct-encoded
unreserved = alphanum / mark
mark = "-" / "_" / "." / "!" / "˜" / "*" /
"’" / "(" / ")"
pct-encoded = "%" HEXDIG HEXDIG
param-unreserved = "[" / "]" / "/" / ":" / "&" / "+" / "$"
phonedigit = DIGIT / [ visual-separator ]
phonedigit-hex = HEXDIG / "*" / "#" / [ visual-separator ]
visual-separator = "-" / "." / "(" / ")"
alphanum = ALPHA / DIGIT
reserved = ";" / "/" / "?" / ":" / "@" / "&" /
"=" / "+" / "$" / ","
uric = reserved / unreserved / pct-encoded

Hi,
Can a TEL URI have the "user=param"?
here param = phone/ip/token
Thanks,
