Call comes from same IP address always.
To comes  form Audiocode:

<--- SIP read from UDP:10.10.0.8:5060 --->
INVITE sip:4 at 10.10.0.4 SIP/2.0
Via: SIP/2.0/UDP 10.10.0.8;branch=z9hG4bKac766808844
Max-Forwards: 70
From: "Z" <sip:7804715665 at 10.10.0.8>;tag=1c766802762
To: <sip:4 at 10.10.0.4>
Call-ID: 7668022781522018162620 at 10.10.0.8
CSeq: 1 INVITE
Contact: <sip:pstn-4444 at 10.10.0.8:5060>

Contact: "sip:pstn-4444"

And it found in sip.conf only:
Found peer 'pstn-9998' for '7804715665' from 10.10.0.8:5060

Is perhaps the name effected by the special character "-" (dash) that is
why it only matches "pstn" and take the first one it found.  Will it
make a difference if I rename the port to pstn_4444 in configuration files.
