Sara,
We don't seem to communicate at the same frequency.
I have nothing else to say.
Good luck.

Thanks Activecat very much .
Now, SIP packets length is varying & RTP packets have fixed length of 87
bytes . Now to input this traffic coming from the soft phone to the
Gnuradio to be processed, i use the UDP source block(to read the UDP
packets from the soft phone port)
in UDP source block , I

Hi Sara,
This is all a little much to explain in Email form properly. PDUs are a
concept from the packet network world. GNU Radio realizes this by using
a combination of asynchronous messages and tagged streams, which is
basically a contract that blocks consume /exactly/ one "chunk" of
samples at
Thanks very much Activecat
I have some last questions please :
1- Does the block " Socket PDU" can be used instead of a socket ? It don't
understand what is the importance of this block ? what does it take as
input ? I know it takes "Pdus"= "Async message " but also I don't
understand what is the

Thanks Marcus Müller , Marcus D. Leech , Activecat.
yes , we can call this "Ethernet to wireless bridge using GSM RF channel ".
I have some questions, please :
1- Can I use both UDP source & TCP source in this way :
Can I connect output of" UDP source" & output of "TCP source" to input of

Hi Sara,
in the stack of usual VoIP systems, there is no such thing as a "RAW"
package.
What you seem to want is the common transport layer for ARP, SIP and RTP
to go over the air.
I'm not really sure why you would want ARP, as that is something two
VoIP devices usually can't communicate over (bec

Hi Sara,
RTP is a complex networking protocol, so you will have to write a
decoder for this, and also for the numerous audio formats that may be
contained within, if you want GNU Radio to actually do something with
the speech within. If you only want

Hi,
I want to capture packets coming from Twinkle Soft phone in gnuradio, these
packet are RTP packets .
But in gnuradio , there is only UDP or TCP source ! I can't find Raw source
to correspond to the RTP packets.
Is there an alternative to RAW source in GNUradio ?
Thanks.
