Asterisk16 PJSIP and Field "Contact:" - need FQDN.
I'm trying to connect asterisk16 and MS DIrectRouter (sip.pstnhub.microsoft.com)..
Asterisk16 build with option:
./configure --with-pjproject-bundled -sysconfdir=/etc --libdir=/usr/lib64
Seeking how to reconfigure PJSIP, so that when sending INVITE, in the "Contact:" field did not enter the IP address, but the FQDN.
For Example.
This is now:
Asterisk16(172.18.1.16)-->NAT[11.22.33.44]-->sip.pstnhub.microsoft.com
This is a SIP INVITE Request to sip.pstnhub.microsoft.com from Asterisk16:
<--- Transmitting SIP request (806 bytes) to TLS:52.114.75.24:5061 --->
INVITE sip:+380770081@sip.pstnhub.microsoft.com:5061 SIP/2.0
Via: SIP/2.0/TLS 11.22.33.44:5061;rport;branch=z9hG4bKPjd2eab8f8-666c-4cb0-94ed-cc747dafcd8a;alias

To: sip:+380770081@sip.pstnhub.microsoft.com
Contact: sip:asterisk@11.22.33.44:5061;transport=TLS
How to change the string
Contact: sip:asterisk@11.22.33.44:5061;transport=TLS
so that it would be in this form
Contact: sip:asterisk@sbc.firma123.com:5061;transport=TLS
?
why do I need it?

......
in the field of Contact there has to be FQDN…
Is it possible to make changes in the configuration file to make this happen?
Or
is it necessary to change the code in the PJSIP source code?
( You can advise where in the source code to change, so that the IP address is not entered into the "Contact" address, but a specific ONE substring sbc.firma123.com )

Please, help to find:
In what *.c module the line is created
Contact: sip:asterisk@11.22.33.44:5061;transport=TLS
?
I want to make change that: ALWAYS, instead of 11.22.33.44 there was a record sss.myrecord.com
