Sipsorcery & callcentric with callerid

Post by shahram » Sun Mar 24, 2013 3:04 am

Hello,

after having some NAT issues with some connections, I decided to create a connection between two accounts through callcentric, so account 1 calls the callcentric sip address that is associated with the 2nd account and connection is established with no sound issues,

however the call is being placed as anonymous, so I wanted send a number in the header as callerid, so the caller can be identified.

but the call fails going into voicemail, I contacted callcentric and they told me the call is being rejected by sipsorcery.

here is what was dialed

Code: Select all

177723xxxxx@in.callcentric.com[fd=3301]


and

Code: Select all

177723xxxxx@in.callcentric.com[fd=1631213xxxx]


and here is what callcentric says how it was rejected by sipsorcery

Code: Select all

1:32 AM Call

The call is being rejected by the sipsorcery server because the incoming call from callcentric has sipsorcery.com in the From header and therefore it gets classified as requiring authentication.

To workaround you could do something like:

Code: Select all

17772325157@in.callcentric.com[fd=3301,fh=somedomain.com]

17772325157@in.callcentric.com[fd=1631213xxxx,fh=somedomain.com]

after they told me that I tried this, but since then somehow all my calls are ending up anonymous, whether I specified a number or not.

but thanks, i am gonna get hold of them asking if they can fix it.

ok this is strange, now I cant say where is the problem, there is no caller id

I contacted callcentric and they told me:
The caller ID that you receive is the same one that we receive. Unfortunately, there is nothing we can do regarding the caller ID that you are receiving.


when I dial

Code: Select all

177723xxxxx@in.callcentric.com[fd=1000]


or

Code: Select all

177723xxxxx@in.callcentric.com[fd=1000,fh=somedomain.com]


I get no caller id,

before this, callcentric was getting the callerid but was being forwarded to voicemail for the call being rejected!
now with no caller id, not even that is happening!

I dont know if they stopped processing the caller id or sipsorcery is not sending them anymore?

my dial out log says

Code: Select all

DialPlan 15:56:09:981 sip1(10360): Commencing Dial with: 177723xxxxx@in.callcentric.com[fd=1000,fh=somedomain.com]


can you send a caller id to callcentric or is it only me not being able to send it?

I also don't get callerid passed through if I call my Callcentric number through in.callcentric.com. It's quite probable that Callcentric have deliberately designed their system like that and they only pass through callerid from trusted sources. Otherwise I could potentially call your Callcentric number from anywhere on the internet and trick you into thinking it was a trusted source calling such as by setting the caller ID to one of your family members or such.

Here's an example of a request I sent to my own Callcentric number:

And the incoming request coming back from Callcentric with the From header anonymised:

I have been working with the nice guys at callcentric to get this fixed and finally here it is :)

I can pass through the callerid with:

Code: Select all

xxxxx@in.callcentric.com[fu=1000,fh=mydomain.com]


even though I was getting it done with fd initially and it was working, right now fd is being ignored and it only works if fu is set to a number.

That's great news, glad it's working. Coincidentally I was reading this thread today http://www.dslreports.com/forum/r281374 ... ng-issues- and saw mention that callcentric do employ some logic on callerid and I suspect that could have been playing a part in this issue as well.

I glad it worked out in the end,

I was starting to think to use DBWrite and DBRead to pass the callerid from one plan to another,

passing it through callcentric would be easier and more accurate.

Hi Shahram/Aaron,
I don't quite understand the purpose of "[fu=1000,fh=mydomain.com]"??
Is "fh=mydomain.com" meant to be "sipsorcery.com"??
And is "fu=1000" meant to be "req.Header.From" ??

How do you set FU to a number? Or can it be *any* number?
Is this fix still applicable? :?:
Ta.

Yes you can still use the fu and fh options in a dial string. The options are described here but in short they both allow you to manipulate a different part of the From header when you send a call. However the From header is used for authentication so if you find your calls get rejected with 401 or 403 responses then you broken it. Also not all providers allow the setting or arbitrary caller ID so even if you set different portions of the From header and the provider accepts it there is no guarantee they will apply that as the caller ID on a PSTN call.
