Hi. I found the error cause. But I still don't know why I have such issue.
When I use my Internet Link (WIFI in my home office), the SIP register message
is sent correctly. Like this:
Session Initiation Protocol (REGISTER)
Request-Line: REGISTER sip:54.233.189.46:5060;transport=UDP SIP/2.0
Method: REGISTER
Request-URI: sip:54.233.189.46:5060;transport=UDP

Opensips got the message above.
However, when I use the GSM mobile network (from VIVO) , some service changes
the content of the SIP Register message. Like this:
Session Initiation Protocol (REGISTER)
Request-Line: REGISTER sip:[64:ff9b::36e9:bd2e]:5060;transport=UDP SIP/2.0

That is why Opensips returns error 500. I guess some service changed IPv4 to
something IPv6.
Could it be caused by the GSM operator (VIVO) ?
What should I investigage to solve this problem?
Any hint will be very helpful !
Thanks alot.

Olá Rodrigo, tudo bem? Saudações de São Paulo!
Opensips doesn't differentiate the network, it will look just to the sip
packet. I recommend you sniff through your packets and check what's different.
Probably there's somenthing on opensips log you didn't get yet, recommend you
take a look there first btw.
About push, I think you're enable push notifications on your device, take a
look: https://www.zoiper.com/en/support/home/article/205/Zoiper%20Push%20Proxy

Hi.
My SIP proxy is an OpenSIPS version 2.4.7. It was 'off' for a while and today I
turned it on again for some tests.
I usually use my home office local WIFI to connect my softphones to the network
and it can be all connected (online) to this SIP proxy.
However, if I use the mobile network (LTE/4G) to connect the softphones to the
SIP proxy, the OpenSIP returns an error 500. That is: "SIP/2.0 500 Server error
occurred (7/TM)".
One of the softphones (Zoiper) allows me to use a kind of "proxy PUSH". If I
use it, the problem is solved even while using the mobile network.
What is a proxy PUSH? Why OpenSIPs return error in a case, but not in the
other one?
What could I do to avoid using a 'proxy PUSH'?
Local WIFI and mobile network come from different carriers.
Any hint will be very helpful!
Best regards.
