Skyetel: Set "From:" and "P-Asserted-Identity" headers

The problem is that I cant dial out to most numbers. The ones that don't go thru give a congested error. The caller ID is all screwed up of the few numbers I can dial to. I contacted Skyetel and they tell me that the issue is on the caller ID not being set when dialing out.

Specifically they are looking for the INVITE packet to contain a "From" and "P-Asserted-Identity" header with proper caller ID, whereas my INVITE packets have the "FROM" header with the channel and username.
This is what they said: https://pasteboard.co/K1kmi5r.jpg

Skyetel is looking for an INVITE packet with: https://pasteboard.co/K1knlhV.png
"From: 'Jose Garcia' <sip:12403403843@SERVERIPREMOVED>"
"P-Asserted-Identity: 'Jose Garcia' <sip:12403403843@ SERVERIPREMOVED>"

Reading thru their knowledgebase setting the proper caller ID in the "From" header is all I need.

How can I set the "From:" header to pass the correct caller ID? Can I set it directly based on the campaign CID?

Thank you in advance

you should edit out your Ip's and such. As for the p asserted identity this is the first ive heard of it. Are you sure your calls are just not going through because of the new stir/shaken technologies that need token authentication? A lot of carriers and using it already and contact is getting less and less

Nope, I forget when but this will materialize very soon. Stir/Shaken will be a requirement soon

I'm taking Skyetel's word for it and assuming this is why. I can dial to some phones, but not all. My neighbor receives the calls and there is no Caller ID CID and sometimes garbage resembling bits of the username set in Account Entry.

UPDATE

I managed to get the P-Asserted-Identity showing by adding this to my acc entry and dialplan:

Added to Account Entry:

Code: Select all

set sendrpid=pai

Full Account Entry:

Code: Select all

[SKYETELOUT]
type=friend
qualify=yes
host=term.reg.skyetel.com
username=7h0xbykg2oj3
fromuser=7h0xbykg2oj3
secret= SECRETREMOVED
dtmfmode=rfc2833
canreinvite=no
disallow=all
allow=g722
allow=ulaw
set sendrpid=pai

Added to Dialplan:

Code: Select all

exten => _775X.,n,SipAddHeader(P-Asserted-Identity: "Jose Garcia" <sip:${CALLERID(num)}@SERVERIPREMOVED>)

Full Dial-Plan:

Code: Select all

exten => _775X.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _775X.,n,SipAddHeader(P-Asserted-Identity: "Jose Garcia" <sip:${CALLERID(num)}@SERVERIPREMOVED>)
exten => _775X.,n,Dial(SIP/1${EXTEN:3}@SKYETELOUT,55,tToR)
exten => _775X.,n,Hangup()


See SNGREP Invite packet https://pasteboard.co/K1m6Lna.png

4th line from bottom you can see that the P-Asserted-Identity is set to SKYETEL's example. Example: https://pasteboard.co/K1knlhV.png

I Still need to figure out

How to replace "7h0xbykg2oj3" (same as user in Account Entry) with the right DID 12162825537 before the @SERVERIPREMOVED ref https://pasteboard.co/K1m6Lna.png

use the SET option in your dialplan, and I can not stress enough how important it is that you do not share information with your IP address to your server. I am a cyber security professional before anything else and I promise you that if i tried right now, I could hack into your server just from the information youve given in this post. Highlight them out using the snipping tool as shown in this example:

Thanks, all of my IPs have been removed.

use the SET option in your dialplan

Ok, I rearranged my question. Thanks for the lead.

Just to be clear I want to replace "7h0xbykg2oj3" (same as user in Account Entry) with the right DID 12162825537 before the @SERVERIPREMOVED ref https://pasteboard.co/K1m6Lna.png
I'm working on finding this out via the "Set" option in the dialplan.

Fixed this! Turns that

Code: Select all

username=7h0xbykg2oj3

causes this behavior, so I took it out.

Current Account Entry:

Code: Select all

[SKYETELOUT]
type=friend
qualify=yes
host=term.reg.skyetel.com
fromuser=7h0xbykg2oj3
secret=SECRETREMOVED
dtmfmode=rfc2833
canreinvite=no
disallow=all
allow=g722
allow=ulaw
set sendrpid=pai

Current Dialplan:

Code: Select all

exten => _775X.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _775X.,n,Set(CALLERID(name)=”Jose Garcia”)
exten => _775X.,n,Set(CALLERID(number)=${CALLERID(num)})
exten => _775X.,n,SipAddHeader(P-Asserted-Identity: ${CALLERID(name)} <sip:${CALLERID(num)}@34.86.97.240>)
exten => _775X.,n,Dial(SIP/1${EXTEN:3}@SKYETELOUT,55,tToR)
exten => _775X.,n,Hangup()


Now the INVITE Packet looks like: https://pasteboard.co/K1msNWZ.png, not sure if the ellipses before and after the CID "...Jose Garcia ..." are important.

IT WORKS NOW!!!!

Glad i could help

As a note on this ticket, we just posted new code to the VICIdial svn/trunk codebase for our integration with TILTX's STIR/SHAKEN service.

Here's the documentation on how it works:
