[Spce-user] incoming Session fails using ngcp CE mr12.4.1 and SIP.js

[Pa Ka]

Hey Please help me to understand this. incoming session on my SIP.js application are failing.

But, outgoingcall are functioning, I can initiate call to the PSTN.

Second, Incoming session works perfectly when using Zoiper softphone application installed on Windows ( Zoiper and SIP.js are using the same configuration from ngcp c5 switch which make me think it is not ngcp c5 issue, but prefer to ask here!!!)

No 404 fallback is enabled on the portal to the specific address used to log into both phone.

This IP 172.110.70.15 , is for a local pc


I'd would like to know if it is SIP.js codes or Sipwise (ngcp CE mr12.4.1 ) configuration that cause the error.  Below are the sip proxy from Kamailio-proxy.log .


When call from PSTN arrives, the script rewrite called party to remove the leading 1

This is the first request to the B2B

New request on proxy for the B LEG of the call - M=INVITE R=<sip:99999101 at 172.110.70.155:57432;transport=tcp;rinstance=6492442;user=phone> F=<sip:calllerNumber64 at sip.sipdomain.com;user=phone> T=<sip:99999101 at sip.sipdomain..com;user=phone> IP=<<null>>:<<null>> (<127.0.0.1>:<5080>) ID=<1B6D3B76 at pstnIP_b2b-1> UA='<null>' DESTIP=<127.0.0.1>:<6052>

After B2B, it fails with this error
