Re: [Sipp-users] REGISTER and Receive an incoming call on SIPp over TLS

[Šindelka P. <sin...@tt...>]

Hello KJM,

I'd suggest you to read 
https://sourceforge.net/p/sipp/mailman/message/34707334/ as it covers 
most of your issue.

The use of TLS may complicate things further, though - I hazily remember 
that I had to patch something in the source code so that sipp could 
initiate outgoing TCP sessions and also expect incoming ones. But on the 
other hand, since you start by sending a REGISTER, the typical use case 
would be that the remote party would not create a new TCP session to 
deliver the INVITE to your scenario but rather reuse the existing one 
created by the REGISTER, so that patch may not be necessary.
