Manipulating P-Asserted-Identity on Dial Verb Header affects From Field

[ajukes]

GIven the following dial verb

{
  "verb": "dial",
  "actionHook": "/outdial",
  "callerId": "+447956697540",
  "answerOnBridge": true,
  "dtmfCapture": ["*2", "*3"],
  "dtmfHook": {
    "url": "/dtmf",
    "method": "GET"
  },
  "target": [
    {
      "type": "sip",
      "uri": "sip:[email protected]:5060"
    }
    ],
    "headers" : {
         "P-Asserted-Identity" : "<sip:[email protected]:5060>"
    }
}

We expect to see a SIP INVITE header as follows

From: <sip:[email protected]:5060>;tag=p3g4cSrZr2c1r
To: <sip:[email protected]:5060>
P-Asserted-Identity: "+1234567890" <sip:[email protected]:5060>

but instead we see a Header as follows with incorrect From

From: <sip:[email protected]:5060>;tag=p3g4cSrZr2c1r
To: <sip:[email protected]:5060>
P-Asserted-Identity: "+1234567890" <sip:[email protected]:5060>

The INVITE sent from the feature server was as expected:

The INVITE from the sbc-outbound app has the improper From header
