SIP Setting to TRUNK setting.... Need help

Hi there,

How do i convert the sip registration setting from my sipura to a inbound/outbound trunk ?

Lets assume i have the following information:

Proxy: sipserver.com
Use Outbound Proxy: yes
Outbound Proxy: 111.222.111.111:5060
Use OB Proxy In Dialog: yes
Register: no
Make Call Without Reg: no
Register Expires: 3600
Ans Call Without Reg: no
Use DNS SRV: no
DNS SRV Auto Prefix: no
Proxy Fallback Intvl: 3600
Proxy Redundancy Method: Norma

Subscriber Information

Display Name: name
User ID: 222222222
Password: 444444444
Use Auth ID: yes
Auth ID: 3333333333

Thanks i’m sure this info will help others as well.

You know maybe specificlly someone could answer these questions:

host=
fromdomain=
fromuser=
authuser=
authname=
username=
secret=**********
dtmfmode= inband
insecure=very
qualify= yes
type=peer
nat=yes
regexten=

Whats the diffrerence between fromdomain and host
and whats the difference between fromuser,authuser, username,authname

Also what are the different DTMFmode

What does insecure=very mean ?

If i’m behind a router do i need nat=YES ?
what is regexten ?

Thanks!
