Hi,
I have not changed res_rtp_asterisk.c Its just that I have put the debug prints in that file. In asterisk 1.8.7.1 the allocation of rtp session is done in check_user_full() function called from handle_request_invite. Since we are not handling the authentication of the user I have called function dialog_initialize_rtp() from handle_request_invite(). I have tried increasing the port ranges but it failed. And the port which asterisk allocates for rtp session is not used by the system(I have checked it using netstat). Please find attached the code snippet of handle_request_invite.

The messages you've posted above don't appear to match what is in the Asterisk source code; if you've modified res_rtp_asterisk.c, then we can't tell you what is wrong if your changes are at fault. However, on the surface this looks very simple: there aren't any RTP ports available for the channel Asterisk was trying to setup. Either you need to increase the block of ports defined in rtp.conf to make more ports available, or you need to ensure that no other application on the system is using the same ports, or both. -- Kevin P.
