3rd party authenticaion and accounting

[tranquilnet]

1. Brekeke Product Name and version:

Brekeke PBX, Version 2.4.3.9 , Multi-Tenant

2. Java version:

N/A

3. OS type and the version:

Windows 2008 R2 Server


4. UA (phone), gateway or other hardware/software involved:

N/A

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :

Pattern 9

6. Your problem:

We utilize a 3rd party authentication and accounting software called RadiusCAT from SVK Software.

We would like to accomplish the following:

1) Use the Brekeke PBX to modify the "To" DID information for an incoming call.

For example, we have am incoming call for +18885551212.

sip:+18885551212@sip.ourdomain.com:5060

For accounting purposes, we want to remove the +1 form the data that is sent to our 3rd party authentication and accounting software.

sip:8885551212@sip.ourdomain.com:5060

Can this be done in the Brekeke ARS/DialPlan rules? If so, how? If not, where else could this be accomplished?

2) Use Brekeke PBX ARS/DialPlan rules to send only accounting information for incoming/outgoing calls for one of our SIP Trunk Providers to our 3rd party accounting and authentication software. All other SIP Trunk provider accounting records will NOT be sent to the 3rd party accounting and authentication software .

Can this be done in the Brekeke ARS/DialPlan rules? If so, how? If not, where else could this be accomplished?

Thanks,

1) dial plan
matching
$request=^INVITE
To= sip:+18885551212@sip.ourdomain.com

deploy:
To=sip:8885551212@sip.ourdomain.com
$session=com.sample.radius.proxy.RadiusAcct
$continue = true

2) dial plan
A. outgoing
matching
$request=^INVITE
$port=^15062
$localhost=^true
To = sip:.+@provider_IP

deploy:
$session=com.sample.radius.proxy.RadiusAcct
$continue = true

B. incoming
matching
$request=^INVITE
$addr = provider_souce_IP

deploy:
$session=com.sample.radius.proxy.RadiusAcct
$continue = true

put the above dial plan on top of others
and disable the current dial plan with radius access
if 1 and 2 are for the same provider, combine them

Thanks! I appreciate your quick reply. I will test it out and get back to you. And yes, it will be for the same provider.

UPDATE:

I have done some testing and below are my results:

1) I was able to get this to work. Thanks! Below is the dial plan I created to remove the +1 from incoming calls:

Matching Patterns

$request = ^INVITE $addr = CARRIER_IP To = sip:(?:\+1|1)(.+)@

Deploy Patterns

$target = 127.0.0.1:15060 $transport = udp $b2bua = true $auth = false $session = com.sample.radius.proxy.RadiusAcct To = %1@MY_SIP_DOMAIN

2) I was not able to get this to work. The reason being is that outgoing calls seem to be a two step process. The first step is the portion of the call that that I need the accounting information to be sent to our 3rd party software, however, the second part of the call includes the information needed to distinguish what carrier is terminating the call per our ARS rules.

For example:

- user 10002704 dials the number 18585551212

PART ONE - DIAL PLAN THAT IS MATCHED:

Matching Patterns

$request = ^INVITE $registeredsender = ^true

Deploy Patterns

$target = 127.0.0.1:15060 $transport = udp $b2bua = false $auth = false &net.sip.fixed.addrport.uac = true

Active Session From:

sip:10002704@MY_SIP_DOMAIN
(76.88.23.48:6704)

Active Session To:

sip:18585551212@MY_DIP_DOMAIN
(127.0.0.1:15060)


PART TWO - DIAL PLAN THAT IS MATCHED:

Matching Patterns

$port = ^15062 $localhost = ^true $request = ^INVITE $outbound = ^true

Deploy Patterns

$auth = false &net.sip.hide.loopback = true $b2bua = true X-PBX-Param =

Active Session From:

sip:MY_OUTGOING_DID@MY_SIP_DOMAIN:5060
(127.0.0.1:15062)

Active Session To:

sip:CARRIER_ACCOUNT#18585551212@CARRIER_DOMAIN
(CARRIER_IP)


Any ideas?

Thanks,

There should be two sessions for each call through pbx

do all calls need radius or only the call from/to this provider?

if use radius accounting for all calls put line $session=com.sample.radius.proxy.RadiusAcct
in default dial plan "To PBX" deploy pattern

if use only for this provider, create another dial plan
matching
$request=^INVITE
To = sip:<pstn_number_pattern>@

deploy:
$session=com.sample.radius.proxy.RadiusAcct
$continue = true

and put it just above default dial plan "To PBX"
need to change <pstn_number_pattern> to the regular expression to only match dialing numbers of pstn call
like if call to this provider need to have a fixed prefix 001, then change To = sip:001.+@

[tranquilnet]

Thanks for you reply, however, after testing I do not see how I can make this work. I could use your assistance further.

The problem I am running into is that I am unable to specify a unique number for my clients/extensions to dial that differentiates carrier A from carrier B. Currently, all users must dial a 1 then the 10 digit number to call US and Canada. Therefor, all numbers dialed look like18585551212.

I have ARS rules setup that all calls withing a max session range are terminated via Carrier A and calls that exceed this max session range are Terminated via Carrier B. This match seemed to be done on the second session of the two sessions of a call when dialed. Is there another way I can send session 1 of the two session call to the radius server if my clients/extensions are dialing the same prefix for outbound calls?

Thanks in advance.

[hope]

create a dial plan and put it just above default dial plan "To PBX"

matching
$request=^INVITE
To = sip:1[0-9]{10}@

deploy:
$session=com.sample.radius.proxy.RadiusAcct
$continue = true

[tranquilnet]

Thanks, however, I am not clear on how this rule will distinguish which carrier the call is being terminated through as this logic happens in the ARS rules after this dial plan is matched from my understanding. Am I missing something?

From what I see in your example, it will match all outgoing calls terminated to both of our carriers. My problem is that I only want calls terminated to carrier B to be sent to accounting and not calls that are terminated with carrier A. Does that make sense?

Thanks!

[hope]

ok, now i know what you need

delete that dial plan and create a new one as below
matching
$port=^15062
$localhost=^true
$request=^INVITE
To = sip:(.+)@carrierB_IP

deploy
$auth=false
$session=com.sample.radius.proxy.RadiusAcct
&net.sip.hide.loopback=true
$b2bua=true

put this one on top all current dial plans whose name include "From PBX ..."

[tranquilnet]

Thanks for your reply.

I created the "To PBX from Carrier A" rule as you described and I am able to get it to match correctly. The problem is that this match is a match for the second session of the two part call and I need to match the first session of the call.

Session Details (PART 1) *I need to match this part of the call only for calls that are terminated via carrier A and not carrier B.

The issue is that I do not see any carrier specific data in Part 1 to do a match. Do you have any other ideas?

Do I need to modify our ARS rules or can I create a single Dial Plan rule that looks at both parts of the call, part 1 and part 2?

Thanks,

[hope]

if you can tell the calls for different carriers, can use dial plan to apply radius for the first part of the call
if use radius accounting on the part 2 of the call makes you cannot know the caller for billing, you can edit ARS for carrier to pass the user to radius and remove the user from From header in the dial plan.
it is better ask svk support about how to pass pbx user to svk radius

Thanks for your quick reply. I just received an email from SVK today about a new release of their software that may resolve the issue. I will keep you posted. Thanks for your assistance.
