Hello,

I am using ser 0.8.14 This is a part of my routing logic:

# send report to table acc, only INVITES and BYES if (method=="INVITE" || method=="BYE") acc_db_request("accounting", "acc");

All INVITES and BYES are logged in table acc for my serweb to access. Then I parse a succesful call by matching the INVITE and the BYE. So far, the method works in all ATAs and hard phones EXCEPT Cisco ATA 186.

If the analog phone connected to Cisco ATA 186 sends the BYE, serweb is UNABLE to parse the BYE and send to acc.

I traced the headers. This is the bye sent by Cisco ATA 186 (Version: v3.1.0 atasip (Build 040211A)). IP addresses to watch: 10.10.6.92 is the IP address of Cisco ATA 186 10.10.6.93 is the IP address of the SIP proxy server 10.10.6.96 is the phone being called (a Grandstream)

Observe the first block above (the instant when Cisco sent the BYE) and compare it to a working BYE sent by another phone. This is the working BYE (note of the first block when the phone sent the BYE):
