             Summary: suspect ps_endpints option rewrite_contact not rewriting with source ip.
                 Key: ASTERISK-30356
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30356
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip, Resources/res_rtp_asterisk
    Affects Versions: 20.0.1
         Environment: debian 10 amd64
            Reporter: Michael


I suspect asterisk and/or pjsip is not rewriting the contact header with source ip address and port when using the rewrite_contact option in ps_endpoints.

I have used this option in the past with success, when address is an internal nat'd 192.168 address.  Recently, using soft phone on cellular data network, i have seen ipv6 ip addresses show up in the sip headers while the source address is indeed ipv4.

SIP packets move back and forth but when answering a call, no audio is passed and asterisk console shows this:

WARNING[4801] acl.c: Cannot connect to 2605:b100:349:5cd1:0:4:375a:3e01: Cannot assign requested address

it looks like the outbound connection is trying to go to an ipv6 address instead of the source ipv4 address.
