Hi.
I have a very similar problem with the topology hiding module and with the
mid_registrar module.
I don’t know if maybe I’m doing something wrong or maybe this is the way it
has to work?. My scenario is as follows:
Private PBX – OpenSIP (Topology Hiding + MidRegistrar) -- UAC
When a REGISTER came from the UAC to the PBX I see something like this:
2020/11/18 09:49:00.290304 192.XXX.XXX.4:51045 -> 192.XXX.XXX.133:5060
REGISTER sip:my.domain.com:5060 SIP/2.0
Via: SIP/2.0/UDP
192.XXX.XXX.4:51045;branch=z9hG4bK-524287-1---300f9ecbae4e0c8d;rport

But then pass through the OpenSIPS with Topology Hiding enabled and
Mid_registrar enabled I see:

As you can see the CONTACT is duplicated and I’m getting the next error:
ERROR:mid_registrar:save_restore_rpl_contacts: 200 OK reply does not
include all req contacts! (ci:
104875NWY1NThmMTJmOWMyNTdlNmY3OGIwZjZlNWIzMzk4NDM)
Nov 18 09:58:00 sbcar /usr/local/sbin/opensips[11924]:
ERROR:mid_registrar:mid_reg_resp_in: failed to process rpl contacts for AoR
'd1.922'
Does someone have a clue on this?

Ricardo

*Asunto:* [OpenSIPS-Users] topology hiding bug?
Dear OpenSIPS development team,
I have come across a strange case that sometime when I use
topology_hiding("UD"), it makes a mistake in changing Contact field.
Scenario is:
A: (Contact: <sip:90006969@172.24.8.5:5060>) sends Invite to private IP of
opensips, opensips changes Contact field to: (Contact: <
sip:90006969.did.29c.2ed2...@public.ip>) and sends Invite from public IP to
B.
Then B sends 200 OK back to Opensips public IP, with correct Contact:
(Contact: <sip:90006969.did.29c.2ed2...@bpublic.ip:5060>). so far so good.
Now Opensips sends 200 OK back to A from its private IP, and changes
Contact to:
Contact: <sip:90006969.did.29c.2ed202e.did.29c.2ed202e@172.24.8.37>
As you see, did part is repeated twice.. and that means when A replies with:
ACK sip:90006969.did.29c.2ed202e.did.29c.2ed202e@172.24.8.37 SIP/2.0
Opensips throws an error: ERROR:dialog:dlg_onroute: malformed route param
[29c.2ed202e.did.29c.2ed202e]
Is this a bug? I am using Opensips 3.1.0.
Thanks,
Mark
