[asterisk-users] SIP 380 Alternative Service with PJSIP

[CDR]

I need to respond with 380 Alternative Service. Is there a way to do
this in PJSIP? Please note that I am not picking up the call. For
instance, the Transfer app closes the call if you did not answer it
first. There is a bug open about this. I want to stay with PJSIP, for
I found that it scales painlessly to 1000+ calls, basically, I have
not found an upper limit yet.
Thanks for your help.
