I have the following setup
client cell phone (PSTN) --sip trunk–> Oracle ACME SBC --sip trunk–> CUCM --sip trunk–> Asterisk -->> Jigasi SIP client
CUCM and Asterisk are in the same network, SIP client is deployed in docker container (it behaves like NAT)
for the sake of it, lets say that
CUCM’s ip: 192.168.1.1/24
Asterisk ip: 192.168.1.2/24
Sip Client’s ips:
When the Sip clients registers it looks like this
-- Added contact 'sip:email@example.com:5060;registering_acc=mydomain_com;x-ast-orig-host=172.18.0.6:5060' to AOR '6000' with expiration of 600 seconds
Sip client is a conference system.
When I call into the conference, my call gets connected but there is no audio because packets are sent to 172.18.0.6 address.
0x7efee03381d0 -- Strict RTP learning after remote address set to: 172.18.0.6:20029
If there is a user inside the conference room connected with computer audio, once the user unmutes his mic, then it gets locked into the sip’s client outside interface and everything works like a charm
0x7efee03381d0 -- Strict RTP switching source address to 192.168.1.3:20029 0x7efee03381d0 -- Strict RTP learning complete - Locking on source address 192.168.1.3:20029
below is my pjsip.conf
[endpoint_internal](!) type=endpoint context=from-internal disallow=all allow=ulaw [auth_userpass](!) type=auth auth_type=userpass [aor_dynamic](!) type=aor max_contacts=1  type=endpoint transport=transport-udp context=from-internal disallow=all allow=ulaw auth=6000 aors=6000 direct_media=no rtp_symmetric=yes force_rport=yes rewrite_contact=yes ; necessary if endpoint does not know/register public ip:port ice_support=yes ; This is specific to clients that support NAT traversal ; for media via ICE,STUN,TURN. See the wiki at: ; https://wiki.asterisk.org/wiki/x/D4FHAQ ; for a deeper explanation of this topic.  type=auth auth_type=userpass password=6000 username=6000  type=aor max_contacts=2 remove_existing=yes
My obvious question is, can I assign a fix ip address to the client? I am guessing no, based on the information I found online. Do you have any suggestions?
