tsearle created an issue (kamailio/kamailio#4232)
### Description
For getting A and B leg QoS stats, Kamailio expects there to be a SSRC key
inside the Stream object.
However some versions of rtpengine (tested with mr13.3.1.1) do not send this
key. Looking at the master version of rtpengine, I see this key has been added
to correspond to ingress SSRCs[0].
This patch adds a checking ingress SSRCs[0] as a fallback if SSRC
### Troubleshooting
#### Reproduction
use kamailio 6.0.1 and rtpengine mr13.3.1.1 using baresip as the calling and
called party
the following in the kamailio.cfg
```
modparam("rtpengine", "mos_A_label_pv", "$avp(mos_A_label)")
#The name of a pseudovariable to hold the minimum encountered MOS value for the
call. The value typically has a range of 1.0 through 5.0.

<!--
If you got a core dump, use gdb to extract troubleshooting data - full
backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
