[SIPForum-discussion] Post Dialing Delay (PDD)

[Mario]

Hi,


Halit, thanks for your fast answer.

It is not exactly a response to the transaction but the time between
the end user dialing the number and receiving the first signalling
message (e.g. RINGING).

Which RFC are you refering to?

Thanks again,
/Mario
