How to change the address to external instead of local in a bunch of Asterisk and JsSIP?

Question

Asterisk

There is Asterisk which calls perfectly through the test service from JsSIP

== DTLS ECDH initialized (automatic), faster PFS enabled
  == Using SIP RTP CoS mark 5
       > 0x7fdafc01dad0 -- Strict RTP learning after remote address set to: :52920
    -- Executing [[email protected]:1] Answer("SIP/199-00000008", "") in new stack
       > 0x7fdafc01dad0 -- Strict RTP learning after ICE completion
       > 0x7fdafc01dad0 -- Strict RTP switching to RTP target address :1150 as source
    -- Executing [[email protected]:2] Playback("SIP/199-00000008", "demo-congrats") in new stack
    -- <SIP/199-00000008> Playing 'demo-congrats.slin' (language 'ru')
    -- Executing [[email protected]:3] Hangup("SIP/199-00000007", "") in new stack
  == Spawn extension (default, 200, 3) exited non-zero on 'SIP/199-00000007'

But when I try to call through this script using my website, the
log changes to the following

== DTLS ECDH initialized (automatic), faster PFS enabled
  == Using SIP RTP CoS mark 5

What could be the difference that two external services give different results? why in one case the external IP is substituted and in the other internal?
