1. Brekeke Product Name and version: SIP Server 2.4.6.7
2. Java version: 1.6.0_03
3. OS type and the version: Windows Server 2003
4. UA (phone), gateway or other hardware/software involved: Audiocodec Mediant 2000
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html : 9
6. Your problem:
User is using a SIP Client from behind NAT. The SIP Proxy sends outgoing calls to an Audiocodec Mediant 2000 SIP Gateway. When the callee hangs up, the Audiocodec sends a BYE message to til SIP Server, and the SIP server forwards it to the caller. However many SIP clients refuse the bye message with a 481 Transaction leg does not exist, presumably because Ondo's BYE message has the Audiocodec's contact address in the FROM field of the BYE message (Ondo's address is placed in the VIA part of the SIP Message but apparantly not all SIP Clients understands this). Other messages from Ondo SIP server to the client (180 RINGING, 200 OK etc) has a correct From enabling the client to understand the SIP Response.
My questions is this: Is there any way to have Ondo send a correct BYE message, where the from part of the BYE message is the same as the FROM part in the 200 OK Messages? |
