SIP-REFER

[newbie]

Anyone have experience sending successful transfers to Twilio via SIP-REFER with carrying the callerID of the customer called from vicidial or incoming caller from vicidial transfer to PSTN (external) via SIP-REFER in twilio trunk?

If so, would be so kind to share dialplan and sip trunk configuration please?

NOTE: calling from Vicidial to Twilio outbound trunk will succeed if the CallerID use is a verified number or purchased from twilio.
When transferring to PSTN using the twilio trunk through blind it will only carry the callerID use (valid twilio DID or verified from them) , which is not a good approach since we don't want to add every single phone number of customer from our leads/manual dialed.

any thoughts?

Try something like this in your dialplan before your dial line


Set(CALLERID(num)=+1${CALLERID(num)}

Good luck

hey Chris,

Tried something like that didn't work. Tried using Transfer() instead of Dial() with no luck . Any other thoughts or sample sip trunk / dialplan you may share?

Striker you around? Striker is there dialplan god, I'm sure he can figure it out.

On the Asterisk side, you need to use the transfer application to generate the SIP REFER. On the Twilio side, make sure to enable this feature and select the desired caller ID. Also, enable SIP debugging on the Asterisk side to ensure the transfer process is completed as expected.

Thanks ambiorixg12,

I apologize for super late post. This is already working in my end. I followed ambiorixg12 post on twilio and use Transfer application. Here's my dialplan for blind transfer.

Code: Select all

exten => 718223344556,1,AGI(agi://127.0.0.1:4577/call_log)
same => n,AGI(agi-set_variables.agi)
same => n,Set(From = +1${CALLERID(num)})
same => n,SipAddHeader(P-Asserted-Identity: +${phone_number})
same => n,Transfer(SIP/+${EXTEN:1}@TRUNKNAME.pstn.twilio.com)
same => n,NoOp(After Transfer: ${TRANSFERSTATUS})
same => n,Hangup

Since this is only. works for blind transfer or No Agent no queue for incoming calls, I was wondering if there's a way it can do warm transfer too ?

Best Regards,

We’re you able to get this sorted out for warm transfers?

I definitely missed your post from 6 months ago. But to answer your questioon is I havent successfully test it yet. I spoke to Twilio support and this is their reply:

" I noticed that you are using Elastic SIP trunking. Unfortunately, for trunking, we only act as a Hop. There is no Programmability at Twilio side. "
