Thanks for your reply. In testing another pbx for different reasons (long story), it was coming back with a "s" for phone number.
Reviewing the phonerlite log, I saw this.
"P-Asserted-Identity: "CID:1231231234" <sip:s@10.10.10.200>"
Where 1231231234 is the CID of the trunk. However the field P-asserted-identity gave some insights.
Freepbx has several options for this entry under
Extension/
extension #/
advanced It was set to
I changed it to
The other option is "no". Setting to "send remote party id header" or no results in the correct number displayed in the logbook, INCLUDING the prefix dialed.
Not sure why other softphone clients treat this differently, perhaps there some other side effects by changing this setting?
Asterisk 15, freepbx 14. Provider for this trunk is "Anveodirect"
