Posted: Tue Oct 06, 2009 5:22 am Post subject: assign a port for RTCP relay |
|
|
1. Brekeke Product Name and version:
Brekeke SIP Server 2.3.7.4
2. Java version:
1.6.0_15
3. OS type and the version:
Linux 2.6
4. UA (phone), gateway or other hardware/software involved:
PJSIP
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :
Pattern
6. Your problem:
Sometimes my router will use different RTCP for Brekeke.
e.g. RTP port: 10000
RTCP port: 10002 (is not RTP+1)
Then the Brekeke RTP always relay to 10001.
I can put the real RTCP port in SDP. So, I can tell Brekeke SIP Server.
Can I assign the RTCP port in the dailplan or using the other way? |

STeven,
How do you specify RTCP port number in SDP?
Can you paste a SDP here? |

Hi lakeview,
a=rtcp:59421 IN IP4 xxx.xxx.xxx.xxx
It's the standard from RFC 3605.
I think Brekeke can't identify the message. |

Yeah.. It seems a bug.
Can you tune RTCP port at your side? |

or..
disable RTP-relay at SIP Server if it is not NAT environment. |

Thanks! But I can't control the NAT mapping and disable the RTP relay...the RTP relay is so important for VoIP...
I want to suggest some customers to use Brekeke SIP Server.
But we don't know their router's action. I think it's hard to control
the NAT mapping.
Hope someone can help the issue... |

who specify "a=rtcp" in SDP?
Is it PJSIP? Is it your router? |
