I need to input the P-Preferred-Identity: sip:2132114400@uc-service.ims.oi.net.br;user=phone;AAA5XSHNBBB os sip header of outgoing call from vital extension to public sip provider.

I already try to add file:

root@pbx:/etc/asterisk/vitalpbx# cat extensions\_\_50-custom\_ppi.conf  
[custom-add-ppi-header]  
exten =\> \_X.,1,NoOp(Adicionando P-Preferred-Identity para ${EXTEN})  
exten =\> \_X.,n,SIPAddHeader(P-Preferred-Identity: sip:2132114400@uc-service.ims.oi.net.br;user=phone;AAA5XSHNBBB)  
exten =\> \_X.,n,Goto(${CONTEXT},${EXTEN},${PRIORITY}+1)

And create an Custom Contexts + Custom Aplications (with personal code) to use the custom contexts and force add P-Preferred-Identity.

For now, no success.

Hi Mo, as your tip it´s works, but when I use ; (semicolon) the header (P-Preferred-Identity: sip:2132114400@uc-service.ims.oi.net.br;user=phone;AAA5XSHNBBB) is not shown.

If I change ; (semicolon) for another character (, comma as example or another simbol) it works, but is not the right sentence for P-Preferred-Identity.

I think that is an bug. I´ll open a vital support ticket.  
Thank you.
