Changing ssrc
Hi Everyone,
We're routing calls through Asterisk (dialing in via sip and then dialing
out via SIP).
We've noticed a curious behavior in chan_sip that doesn't persist with
chan_pjsip. When examining the packet capture, we're seeing the SSRC
changing constantly on the call. At first it happens over a variable
interval (15s 6s etc) but eventually it ends up changing exactly every
1000ms. Every time the SSRC changes, it causes a very minor but
noticeable gap in audio.
The fact that it's changing on this exact interval makes me thi...

Googled around for this strange error meesage with no
helpful results at all...
Does somebody has any idea what this means?
"Forcing Marker bit, because SSRC has changed"
At the same time I only get inbound audio but other
side can't hear me...sometimes I just hear my echo
and nothing from other side...
Asterisk version 1.2.9 and both participants with
public IP addresses...so no NAT/Firewall involved...

SIP One-way audio: == Forcing Marker bit, because SSRC has changed - trxtel.com
Dear list (and more specifically Bret),
I am getting one-way (inbound only) audio when trying to place a SIP call
via voip.trxtel.com (i.e. 18005558355@voip.trxtel.com). The Cli spits out
"== Forcing Marker bit, because SSRC has changed" 5 times after atempting a
native bridge. I realize this is most certainly a NAT issue, the * server is
behind one. Sip.conf has externip=, and localnet=.
Can someone explain what SSRC changing implies is going on, and why it
affects NAT? This is actually the first NAT issue I hav...

changing of ssrc between early-media and call media
...answers, for a few seconds (4/5 sec typical) some SIP
client could not hear anything (the ringing was heard well!), then the
audio comes back again with no problem.
Looking for any differences between the behaviour of version 1.4.17
and 1.4.19 I found that in the new version the RTP stream changes SSRC
between the early media session and the actual call session. This
seems to me quite pretty, and a major part of SIP clients seems not to
be disturbed by it. Anyway I'd like to ask you a couple of things on
this issue:
1) Is the changing of ssrc standard compliant? (I suppose yes, because

RTP timestamps
...should be, but
sometimes while the asterisk plays MOH (or somebody transfers call to
another extension) the timestamps on RTP packets will fall to past.
Providers media gateway dosn't like that. The marker bit is correctly
set but it seems like that dosn't change anything. Sequences and SSRC-s
are Ok, no packet loss. Has anyone seen something like this before and
knows what is the cause and how to fix this?
I've tried many changes in config and upgraded to 1.6.1 but it didnt
change anything, currently running asterisk 1.4.26.1 on 64 bit intel
platform with opensuse.

Sipura g729 call quality to PSTN
If this has been covered before - I appologize.
We use some Sipura SPA-2000's with the g711 codec and all seems fine
(except for the occasional failure to register errors in my asterisk
logs - but I will save that for another post).
g711 call quality is on par with our Cisco 7960's. However, when
using the g729 codec, the call quality on the Sipura device goes
downhill on the PSTN side
