[OpenSIPS-Users] From a moment OpenSIPS ignores one end of the communication

[Jorge Luis Ortea]

Hi all,

Very strange case, OpenSIPS in the middle SIP transaction ignores one end of the communication.

The schema is very simple, OpenSIPS exchanges SIP traffic between another OpenSIPS (with a passthrough T38 Asterisk behind) and a SBC, during a T38 fax call.

The sniffer on the Opensips interfaces shows that the packets are arriving correctly.

In the capture can see the packets with red arrow are ignored, not even writes in log, as if this packet did not exist, it always ignores the same SIP packets, all calls are same.

Without firewall, selinux, ip or port changes ....

A curious detail, from a moment Opensips ignores packets from 10.201.198.60, however after BYE packet seems that it manages SIP packets again.
