P-Asserted-ID header

Hi,

I looked in chan_sip.c but found nothing. Does Asterisk support the P-Asserted-ID header? Does anyone know how to send a caller_ID in this field? Thanks

I found the answer to my own question:

Hopefully someone would implement it in chan_sip.c, my service provider requires it.
