Windows 10: With Windows 11 can I setup a port to receive RTP packets?

I want to check the RTP packets on a Windows PC.So i would like to configure a Port that can receive them and then analyze them.Maybe I need some additional SW?

Getting RTP(UDP) port error when using softphone calling.

One of our customer they have installed our application in citrix xendesktop setup(OS-windows server 2016) and they are getting RTP port busy error when softphone calling. we have tried to configure 3rd party softphone. But the same issue. As per our analysis it seems the OS issue.

Issue details-

APP requests a UDP socket with a local port of XX

Windows says okay and gives the UDP socket but with port XY

APP now sends an INVITE with SDP containing XX as a destination port for RTP

It receives an OK with SDP where the port for media on the other participant is YY

So now a call is established

APP sends media from port XY to YY



so other participant is able to hear, the other end sends on xx



but other participant sends RTP from YY to XX which goes nowhere

---------------

So can you please help us, how and what configuration will do, so that we can resolve this issue.

Citrix version - 7.18 OS- windows server 2016 client os- win10

 

Unable to receive traffic to UDP port 4500

How can we prevent Windows from interacting with packets received on UDP port 4500?

Tested on other UDP ports, all can correctly receive data, while using UDP port 4500, no data can be received.

Have already tried

1. Stopping IKE and AuthIP IPsec Keying Modules.

2. Stopping IPsec Policy Agent.

3. Stopping all firewalls

But all failed to u receive data although it can bind to port 4500

Seems that windows some how drop packets received from UDP port 4500

How can we solve this issue

i receve sip invate



v=0

o=Nokia-SIPUA 9 3 IN IP4 82.150.184.16

s=CounterPath X-Lite 3.0

c=IN IP4 82.150.184.16

t=0 0

m=audio 30494 RTP/AVP 0 101

c=IN IP4 82.150.165.7

a=sendrecv

a=ptime:20

a=maxptime:200

a=fmtp:101 0-15

a=rtpmap:0 PCMU/8000/1

a=rtpmap:101 telephone-event/8000/1

a=x-sipx-ntap:X82.150.165.7-82.150.165.7;4



and my friend receve 200OK



v=0

o=Nokia-SIPUA 9 3 IN IP4 82.150.184.16

s=CounterPath X-Lite 3.0

c=IN IP4 82.150.184.16

t=0 0

m=audio 30494 RTP/AVP 0 101

c=IN IP4 82.150.165.7

a=sendrecv

a=ptime:20

a=maxptime:200

a=fmtp:101 0-15

a=rtpmap:0 PCMU/8000/1

a=rtpmap:101 telephone-event/8000/1

a=x-sipx-ntap:X82.150.165.7-82.150.165.7;4



in both packets is specified

m=audio 30494 RTP/AVP 0 101

c=IN IP4 82.150.165.7



but nokia e51 send rtp stream directly to 10.69.1.1



is posible change behevior of sip client or is it bug?



thank you
