PJSIP syntax error exception when parsing 'From' header on line 4 col 54

Asterisk Asterisk SIP

I have a problem with registration of one type of embedded device (Lara Intercom) - log below. Only non-standard thing in From field for me is that tag contains “@ip address” marked with **. Can this be solved on asterisk side?

ERROR[590]: pjproject: : sip_transport. Error processing 425 bytes packet from UDP 192.168.1.241:5060 : PJSIP syntax error exception when parsing ‘From’ header on line 4 col 54:

You might be better off letting LARA not register, and, instead, assign static IP.

Can you edit your post and use the preformatted feature of the SIP? I do not know if you had four or just two stars at the end of the From line.

Of course, you could dig down into the source code of PJProject and remove that check. That is a lot of work and depends on your coding skills. Or are you asking how to solve that actually?

By the way, What does the manufacturer of that SIP user agent say about this?
