[Freeswitch-dev] offering two "m=" lines from FreeSWITCH

Hi, I am new to FreeSWITCH, I was just wondering that can we initiate Best Effort SRTP offer from FreeSWITCH in the same way as Polycom phones do, i.e sending two "m=" lines for the same media, the first line having a SAVP profile, while the second one having the normal AVP profile. Kindly please let me know how can i do this. Thanks in advance. Regards, Ujjwal
