This is never attempting to call the second endpoint:
1709c7c4-fa17-11e5-9184-9d31ebce310e 2016-04-04 11:41:28.831214 [DEBUG] switch_ivr_originate.c:3750 Originate Resulted in Error Cause: 606 [USER_NOT_REGISTERED]
It then tries to negotiate the ice session with freeswitch, as it is trying to answer the call locally and send it to voicemail. then we have:
1709c7c4-fa17-11e5-9184-9d31ebce310e 2016-04-04 11:41:28.831214 [DEBUG] switch_core_media.c:3380 sofia/internal/anonymous at 192.168.199.22 no suitable candidates found.

the issue is your box is on a rfc1918 ip, and the default candidate acl's do not consider those valid. You will need to adjust the acl if you plan on having freeswitch as a server answering webrtc calls from private address space.
