I recently setup an ATA equipament in my Asterisk 13 PJSIP behind NAT, and this equipament is lost the connection after the default_expiration time that was 2 minutes.
I was check it and observed that this equipment is not answering for SIP OPTIONS monitoring, I don’t know why because when the equipment register is sent a packet of SIP OPTIONS then the endpoint answer 200 OK, then in the next packets none answer is received.
First SIP OPTION = answer 200 ok

Second attempt to SIP OPTION = no answer

Anyone used that and worked well? Is it possible I disable the SIP option for PJSIP?
In the same internal network we have other VoIP telephones working well.
