Trunking with other SIP Server

[indo]

Hi,

Pardon me for the newbie question, but i have a challenge to configure interconnection from 3CX with other SIP server (perhaps it is an OpenSIPS with Asterisk), i already search through google and asking at other place and found that Generic SIP Trunking is the solution for this problem, but i couldn't found the complete guide for trunking to other local SIP server, i only found the guide for the VoIP provider with long trunking number that start with 9 (*9xxxxxxx).

Does anybody have the standard complete guide for trunking with other SIP server for a newbie like me? Thank you master.

cut and paste from another site, pretty sure that's what I did.

Setup:
Office 1 - Elastix 1.6.2-27
Extensions 200-399 range
PRI/T1 connectivity (want to use this from Office 2)

Office 2 - 3CX version 9
Extensions 400-499 range
No PSTN connectivity

Need to dial extension-to-extension both intra and inter offices.
Need to dial outside with different CallerID for each site (only works using PRI type service).

Elastix (Office1):
1. Create Trunk leaving everything blank except these:

Trunk Name: Office2
PEER Details:
type=friend
insecure=very
host=<Office2 3CX ip>
context=from-internal

Submit

2. Create Outbound Route
Route Name: ToOffice2
Route Password: <Blank>
Intra Company Route: <checked>
Dial Patterns: 4XX <or whatever your extension range is>
Trunk Sequence: SIP/Office2

Submit/Apply Configuration Changes


3CX (Office2):
1. Create new VOIP Provider
Name of Provider: Office1
Select "Generic SIP Trunk"

Next

SIP server hostname or IP: <Office1 Elastix ip>

Next

External Number: DID or CallerID any unique number
Authentication ID: same
Authentication password: <Blank>
Maximum simultaneous calls: 1 or more, I used '50'

Next

Office Hours: Choose whichever is appropriate
Check "Same as Out of Office hours" box (if you want)

Next

Starts "Outbound Rule" wizard automatically:

Rule Name: <toOffice1>
Apply this rule to these calls:
Calls from extension(s): 400-499
Make outbound calls on:
Route 1: Office1
Strip Digits: 0
Prepend: <Blank>

Finish

2. Open VOIP Providers | Office1
Select Tab [Source ID]
Check "Source identification by DID" box
SIP Field containg DID numbers: "Request Line URI : User Part" (Default)
Select "Add Mask" button
Source ID mask: *

Select Tab [DID]
Enter each extension number here <e.g.: 400, 401, 405, etc.>

OK

Done.

Go to Ports/Trunks Status and make sure it is green, if it is then start testing.

CALLER ID Fix:
Set main Zap Trunk to Office2 (3CX) desired CallerID info.
Set each extension in Office1 (Elastix) callerID info to desired CallerID for that office, individually controlled only at Elastix end becuase it had the PRI trunk.

Also set each extension's "Outbound Caller ID" in Office2 (3CX) to the desired Caller ID for internal calls.
Go to: Extension Number <400> and select Tab [Other], fill in the Outbound Caller ID (we used First Name).

Now when calls are internal in either office or from office to office it shows the proper Caller ID info.
