Hi Dan, We're currently debugging this also with Snom 3XX/8XX on Draytek 2820 routers: http://jira.freeswitch.org/browse/FS-3552 On 9 September 2011 00:17, Dan Lan <danlanweb@gmail.com> wrote:
Hi, Anthony:
Thanks for your direction. Could you give me a little bit more info about where to set the parameters?
What I did was, I put the incoming GW IP into my ACL list, so my FS will accept call from the GW. I then create a public dialplan to transfer the incoming DID to a registered SNOM phone with public IP address. <extension name="my_incoming_did"> <condition field="destination_number" expression="^(999\d{10})$"> <action application="transfer" data="$1 XML default"/> </condition> </extension>
After I add <action application="set" data="disable_rtp_auto_adjust=true"/> before action "transfer"
The RTP flow become like this. GW(5416) --> FS (31326) FS (31326) --> GW (5418) This looks work fine on Leg A now without auto change the port (the incoming leg) However, something also change down the road on Leg B. Now I got SNOM(52934) --> FS (21464) NO ANY RTP from FS --> SNOM ...
So now I still got one way voice, but is exact other way around. Before change, the Leg B is working fine.
My question is where shoud I put rtp_manual_rtp_bugs=accept_any_packets ? Do I have to put togerther this with disable_rtp_auto_adjust?
Did you just fix this problem (because you mentioned using today's git), so I need to re-compile the most current git to fix this? (I am in window version)
Thanks again. Dan Lan On Thu, Sep 8, 2011 at 2:02 PM, Anthony Minessale <anthony.minessale@gmail.com> wrote:

Hi, I run into a weird situation. My media gateay handle voice call with 2 different RTP ports for send & receive
Here is what happened. (ps: both gateway and FS are all on public IP, no NAT involved) 1. Incoming call INVITE from gateway to FS Connection Information (c): IN IP4 100.100.100.100 (This is my media gateway IP address) Media Description, name and address (m): audio 5294 RTP/AVP 18 0 4 2. FS response with session progress with media information Connection Information (c): IN IP4 200.200.200.200 Media Description, name and address (m): audio 22428 RTP/AVP 0 3. I start to see some RTP traffic exchange between FS and GW from FS (22428) --> GW (5294) from GW (5292) --> FS (22428) please note: the GW use two DIFFERENT PORT for RTP, one for sending and one for receiving 4. For a while (about 5 secs, I think) The RTP flow change on FS side to become, (there is no RTCP packet during the time) from FS (22428) --> GW (5292) from GW (5292) --> FS (22428) In other word, the FS now sending RTP to 5292 instead of 5294 (which was intended in INVITE SDP message)
And, of course, I cannot hear the voice on GW side after this.
Anyone encounter this before? Are there any paramaters that might involved in this auto changing RTP port behavior of FS?
Any direction for me is appreciated, I will play around with this, and post back my result to community.
