Description

When making end-to-end IMS voice call over IPv6, Kamailio PCSCF doesn't send the Sip Invite to callee. I saw the following error in PCSCF logs:

4(32107) DEBUG: [parser/parse_uri.c:1258]: parse_uri(): parse_uri: bad char ':' in state 2 parsed: sip:FC00:1234 (13) / sip:FC00🔢3:2:0:0:0:0:5060 (30)
4(32107) ERROR: tm [ut.h:254]: uri2dst2(): ERROR: uri2dst: bad_uri: [sip:FC00🔢3:2:0:0:0:0:5060]
4(32107) ERROR: tm [t_fwd.c:1737]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches
4(32107) DEBUG: tm [t_funcs.c:331]: t_relay_to(): t_forward_nonack returned error -478 (-478)
4(32107) DEBUG: tm [t_funcs.c:348]: t_relay_to(): -478 error reply generation delayed

I saw a similar issue in your database: nat_traversal: Builds wrong URI for IPv6, bad URI parsing #362.
Have you fixed this issue?

Troubleshooting

To me, sip:FC00🔢3:2:0:0:0:0:5060 should be sip:[FC00🔢3:2:0:0:0:0]:5060. After I added the workarround to change it to sip:[FC00🔢3:2:0:0:0:0]:5060, PCSCF can send the Sip Invite to callee and the IMS voice call can be established.

Reproduction

I can reproduce this issue using two soft phones: Linphone and Jitsi.
