questions about voip router configuration, thanks !!!

1. see this configuration:

dial-peer voice 1 voip

destination-pattern 555

session target ipv4:10.10.1.1

dial-peer voice 2 voip

destination-pattern 5551212

session target ipv4:10.10.1.2

if in "two stage dialing" , the dialed string "5551212" will match peer 1

because of the "digit-by-digit" nature, am I right?

if in "DID" mode, dialed string "5551212" will match peer 2, because of the

"longest match rull". am I right?

2. see this configuration:

dial-peer voice 1 voip

destination-pattern 555T

session target ipv4:10.10.1.1

dial-peer voice 2 voip

destination-pattern 5551212T

session target ipv4:10.10.1.2

the dialed string "5551212" will match dial-peer 2, no matter it's in

"two stage dialing" or "DID" mode, because of the "longest match rull",

am I right ?

if there is a "T" following the destination-pattern, the "longest match rull"

will work no matter it's in "two stage dialing" or "DID" mode , am I right ?

3. see this configuration:

dial-peer voice 1 voip

destination-pattern 555$

session target ipv4:10.10.1.1

dial-peer voice 2 voip

destination-pattern 5551212$

session target ipv4:10.10.1.2

if it's in "two stage dialing" mode , dialed string "5551212" will match the

dial-peer 1 ,because of "digit-by-digit" nature, am I right ?

if it's in "DID" mode, dialed string "5551212" will match dial-peer 2,

am I right ?

what is the use of "$" ? i can not see what's good about "$" ?

4. When the call is coming from PSTN, if it's in "two-stage-dialing" the number

collecting is "digit-by-digit". if it's in "DID" mode the whole dialed number

is used to match the outbound dial-peer, am I right ?

But if the call is coming from ip network, how is the number collected ?

is it "digit-by-digit" or "the whole number used" ?
