FreePBX Trunk settings for SunRocket

In order to get FreePBX working with SunRocket one needs to set up the trunk correctly. Here are the settings I have working at the moment. This is assuming you have the Innomedia Gizmo. These may work for users with other ATAs, but I can't say for sure.

1)Edit sip.conf and add or modify the useragent line to:

useragent=InnoMedia SIP MTA6328-2Re v3.0.77

2) Add a SIP trunk with the following:

Trunk Name:    sunrocket

PEER Details:
 allow=ulaw
 authuser=<AuthID>
 disallow=all
 dtmfmode=auto
 fromdomain=sunrocket.com
 fromuser=<UserID>
 host=67.133.234.125
 insecure=invite
 nat=1
 outboundproxy=67.133.234.125
 secret=<Passwd>
 type=friend
 username=<AuthID>

Incoming Settings: all blank

Register String: <UserID>:<Passwd>:<AuthID>@sunrocket.com/<UserID>


where:
<AuthID>    is the AuthID from the Innomedia (basically extended account number)
<UserID>    is essentially your 10 digit SunRocket telephone number
<Passwd>    is the Passwd from the Innomedia

That's all the required settings. The difficulty may be though that if your <Passwd> is like mine, it contains equal signs (=). The currently released version of FreePBX (2.2) has a bug that prevents PEER Details from having values that contain equal signs. See trac bug report for the details and the fix.
