ARS, Dial Plan and ITSP

[GenesisMO]

1. Brekeke Product Name and version: PBX Version 2.4.3.9

2. Java version:

3. OS type and the version: Windows 7 64-bit

4. UA (phone), gateway or other hardware/software involved:
X-Lite UA (3 of them), one in WAN and 2 in LAN, 1 ITSP connection (Broadvoice)

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

6. Your problem:
We are trying the PBX version, and we are having a hard time figuring our the relationship between ARS and Dial Plan when it comes to setting up an ITSP (Broadvoice).
So far, we are able to register the PBX with Boradvoice, as well as call in. However, calling out does not work with any of our UA (we have 3 configured so far, all X-Lite).
Is there some good tutorial out there on the Brekeke ARS and Dial Plan?

I think I figured out what the problem is:
I wiresharked the PBX unit while placing a call out. It seems that the INVITE request from my client does not go all the way to the Broadvoice server, but only to the PBX server. Should I not be seeing the IP of the Broadvoice in the Destination rather than the IP of the PBX?

thanks for anyone who can shed some light.

Hello,

I hope to help you understand the relationship of the pbx(ars) and the sip server(dial plan).

Calls flow in and out of your pbx thru the sip server dial plan.
When a registered ua makes a call then the call flows from the ua to the sip server to the pbx back out the sip server to the VSP. You can see the IN and OUT designations in the sip server dial plan.

When a ua makes a call it comes in the sip server, then flows to the pbx looking for a match.

Here is an example:
You have two VSPs, Voipwell and Vonage.
Voipwell is set up in the ARS matching patern like 9(.+)@ and vonage is setup up in the ARS matching pattern like 8(.+)@. When you want to use Voipwell, then put a 9 in front of the telphone number so to dial a phone number like 5702135155 if you want to use Voipwell have xlite dial 915702135155 or if you want to use Vonage dial 815702135155. Notice the 9 and the 8 are outside the ( ) so they get stripped off before the calls are actually sent to Voipwell or Vonage.

If you set up login authentication with your VSP(name and password) then no changes to the Brekeke default Sip Server dial plan is necessary. If you use ip authentication with no login and password, then for security reasons, the sip server needs to have and entry allowing calls from the VSP's ip address to come thru. It's all in the SIP server dial plan tutorial.

I hope this helps.

what response can you see in wireshark when you make outbound call with broadvoice?
is there prefix 9 in broadvoice ARS pattern-out/mathching pattern?
if yes, you need to dial 9 before destination number
if no, just dial destination number directly

[GenesisMO]

Thanks, Hope.
I actually see that the 9 didn't get stripped out, and the IP in the "destination" column of the wireshark trace is that of the PBX, not of Broadvoice.
It seems that based on what Voipwell also explained, there is a missing session from the PBX to Broadvoice....

[hope]

can you paste your broadvoice pattern-out used for outbound call here?
and if you dial destination pstn number directly without 9, can the call go to broadvoice?

I only have a Pattern-OUT in the ARS section of the PBX. I do not have anything in the Dial Plan of the SIP Server specifically for Broadvoice. Do I need to have or should there be something basic out-of-the-box that takes care of it?

Here is the pattern:
Matching:
To: sip:([0-9]{7,25})@

Deploy:
From: "xxxyyy1234"<sip:xxxyyy1234@sip.broadvoice.com>
To: sip:$1@proxy.dca.broadvoice.com

Thx again!

Hope,

Thanks for your reply. I actually got it to work 10 minutes ago after tinkering some this afternoon.
Here is how my ARS looks now.

Matching:
To: sip:9(.+)@

Deploy:
From: "xxxyyy1234"<sip:xxxyyy1234@sip.broadvoice.com>
To: sip:$1@proxy.dca.broadvoice.com

I think the key was to modify the pattern to recognize the 9, and also change the priority to process it first.
xxxyyy1234 is the DID I got from Broadvoice.

Thanks for everything!

[GenesisMO]

correction: I did a bad cut-paste - the correct deploy pattern is:

Deploy:
From: "xxxyyy1234"<sip:xxxyyy1234@sip.broadvoice.com>
To: sip:$1@sip.broadvoice.com

glad to know it works.

it seems there were other ARS pattern-out with prefix 9.
if running several ARS pattern-out at the same time and route call to different destinations, it is better use different prefix for each pattern-out. otherwise, pbx will match to the one with higher priority.
