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 [Resent Packet: False] Message Header Via: SIP/2.0/UDP 192.168.1.103:5060;branch=z9hG4bK-524287-1---6dbfa766cffddeee;rport Max-Forwards: 70 Contact: <sip:55555@192.168.1.103:5060;rinstance=1afa98b2b6d17a34;transport=UDP> To: <sip:55555@54.233.189.46:5060>;transport=UDP> From: <sip:55555@54.233.189.46:5060;transport=UDP>;tag=98bfc34c Call-ID: H1E0jkwiMniiyT5az1BT7g..

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 Method: REGISTER Request-URI: sip:[64:ff9b::36e9:bd2e]:5060;transport=UDP [Resent Packet: False] Message Header Via: SIP/2.0/UDP [64:ff9b::c000:4];branch=z9hG4bK-524287-1---0a8189adf6c3449a Max-Forwards: 70 Contact: <sip:55555@[64:ff9b::c000:4]:5060;transport=UDP;rinstance=ffaac43f13178e89> To: <sip:55555@[64:ff9b::36e9:bd2e]:5060> From: <sip:55555@[64:ff9b::36e9:bd2e]:5060>;tag=f19aea4d Call-ID: VICBinZsDk5_ZhpHGd__CQ..

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.

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 Regards On Wed, May 11, 2022 at 4:13 PM Rodrigo Pimenta Carvalho <pime...@inatel.br<mailto:pime...@inatel.br>> wrote: 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.
