[5.2] 200 Ok on Re-invite faces "transaction not found - (branch -1)" when topos module is used
My setup is UAC --> Kamailio SBC --> External PBX
When external PBX sends 407 Proxy Autehtication required , the kamailio SBC sends another invite with auth header ( uac module ) and updated cseq ( from dialog modules track_cseq_updates ). To this the external PBX replies with 200 OK . However Kamailio SBC drops this 200 ok with "t_reply_matching(): failure to match a transaction" and "reply_received(): transaction not found - (branch -1)".
I am using Lua engine but problem is reproducible even with plain config file based routing configuration
Reproducible everytime with uac module working with uac and topos module from v5.1 and above.
Sample parameters declaration I am using is like
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "track_cseq_updates", 1)
modparam("uac","auth_username_avp","$avp(auser)")
modparam("uac","auth_password_avp","$avp(apass)")
modparam("uac","auth_realm_avp","$avp(arealm)")
modparam("topos", "storage", "redis")
modparam("topos", "sanity_checks", 1)
modparam("topos_redis", "serverid", "sbc")

Not sure if the callflow will appear disfigured below. Primarily what it depicts is that 200 ok from External PBX is dropped by Kamailio and hence kamailio tries to resen the auth based invote multiple times till request timeout occurs

By monitoring redis, I can see that compacting headers by topos and tps storage C file on redis is only happening for the branch id of the first invite , such as
"HMSET" "b:x:z9hG4bK68dc.5ad386873790061ba2a8f1d254ec3300.0" "rectime" "1559887868" "a_callid" "OWY3ZTQ3NGM3NTg0N2U3YmE2MTBiOTIxMTRkOGZmNjM" "a_uuid" "atpsh-5cf9fea7-123a-1" "b_uuid" "btpsh-5cf9fea7-123a-1" "direction" "0" "x_via" "SIP/2.0/TCP <uac_pvt_address>:9364;received=<uac_pub_address>;branch=z9hG4bK-d8754z-e7184457335bac6a-1---d8754z-;rport=29567" "x_vbranch" "z9hG4bK68dc.5ad386873790061ba2a8f1d254ec3300.0" "s_rr" "<sip:<kamailio_pub_address>:5060;r2=on;lr;ftag=e0090423;did=508.39e1;nat=yes>,<sip:<kamailio_pub_address>;transport=tcp;r2=on;lr;ftag=e0090423;did=f4d.fe9;nat=yes>" "x_tag" "45a56f2c" "s_method" "INVITE" "s_cseq" "1" "a_contact" "sip:6666666666@<uac_pvt_address>:9364;transport=tcp;alias=<uac_pub_address>~29567~2" "as_contact" "<sip:atpsh-5cf9fea7-123a-1@<kamailio_pub_address>;transport=tcp>" "bs_contact" "<sip:btpsh-5cf9fea7-123a-1@<kamailio_pub_address>:5060>" "a_tag" "45a56f2c"
But when the 200 ok for re-invite comes back after authentication, the topos module tries to extract the records for new branch cseq such as
"HGETALL" "b
which is obviously not set and hence not fetched resulting in transaction not matched error and 200 ok being dropped.
If topos storage can HMSET for newer branch id as they are created, I presumme it should fix things up and matching transactions will be ok
