Hello I got the following errors when trying to register my SIP trunk. I use Vodafone Italy as provider.
[2025-08-05 13:13:40] ERROR[4228] res_pjsip.c: Unable to create outbound OPTIONS request to endpoint +3908******** as URI 'sip:+3908********@[email protected]:5060' is not valid
[2025-08-05 13:13:40] ERROR[4228] res_pjsip/pjsip_options.c: Unable to create request to qualify contact sip:+3908********@[email protected]:5060 on AOR +3908********
Possibly
will help.
still the same problem
Please post screenshots of your trunk pjsip settings, both General and Advanced tabs.
Mask username and secret but leave other settings visible.
You have two @'s in the URI, but there can only be one, immediately before the domain name. From the article quoted, they don’t expect @… in the user part of the URI, but they may require it in the auth user name.
Any @ in the user part of the URI would need to be escaped as %40, but it looks like they don’t need the @, at all.
Please check
