Hi,

I'm using JsSIP from a webpage to make a SIP call to FS, using OverSIP as a Websocket->SIP proxy.

I'm able to Register successfully, but when I make a call from JsSIP UA to FreeSWITCH, I get a 180 Ringing, but after that I get a 488 Not Acceptable here.. Please help me figure out what I'm doing wrong here.

My inbound_codec_prefs is :

<X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,G7221@32000h,G7221@16000h,G722,PCMU,PCMA,GSM,isac@16000h,isac,opus"/>

Here is FreeSWITCH's log for the incoming call :
