Sverre G commented on ASTERISK-13684:
-------------------------------------

I've recently upgraded to the latest version of Asterisk, and noticed the my extensions.conf wasn't working correctly on forwards, and it's because I was previously using 1.4 with this patch... but the latest version doesn't have this patch committed into the trunk.

Why did this not get committed to trunk? Will this patch work on Asterisk 11.2.1?

> Hi!
> When a blind transfer is initiated from a SIP, often the name of the transferer is needed (e.g. billing, applying restrictions ...). Currently there is a variable called SIPTRANSFER_REFERER which contains the value of the Refered-By header - but this variable is not trustworthy, as the SIP client can put anything into this variable.
> Attached patch adds the variables SIPTRANSFERER_PEERNAME and SIPTRANSFERER_USERNAME which contain the respective SIP username (peer or user)
> ****** ADDITIONAL INFORMATION ******
> As I am not up2date with the current peer/user behavior maybe the SIPTRANSFERER_USERNAME can be removed. I greped the code and it seems that p->peername is also set in case of a SIP user, but not vice versa.
