[Spce-user] sst issue in version 2.8

[Jon Bonilla (Manwe)]

Hi all

I'm experiencing a sst problem with a peer in version 2.8. trying to debug it I
realize that sems is not adding sst negotiation in the INVITE request nor the
200Ok to the caller. Seems like it's ignoring the sst parameters.

Sample call from subscriber to PSTN:

Sessions Timers enabled for caller with interval 300 and method
UPDATE_FALLBACK_INVITE

Sessions Timers enabled for callee with interval 1800 and
method UPDATE_FALLBACK_INVITE

Writing sbc
parameters  ;aleg_sst_enable=yes;aleg_sst_expires=300;aleg_sst_min_timer=90;aleg_sst_max_timer=7200;aleg_sst_refresh_method=UPDATE_FALLBACK_INVITE;sst_enable=yes;sst_expires=1800;sst_min_timer=300;sst_max_timer=7200;sst_refresh_method=UPDATE_FALLBACK_INVITE 


And the generated doesn't contain sst info INVITE:


U 2015/09/23 03:35:08.008827 127.0.0.1:5080 -> 127.0.0.1:5060

From sems log:

[onInvite, SBC.cpp:192] DEBUG: using call profile 'ngcp' (from matching
active_profile rule 'ngcp')

No refers to sst while processing INVITE. I can send full debug log in private.



From Sems ngcp sbc profile:

enable_session_timer=$P(sst_enable)
session_expires=$P(sst_expires)
minimum_timer=$P(sst_min_timer)
maximum_timer=$P(sst_max_timer)
session_refresh_method=$P(sst_refresh_method)

enable_aleg_session_timer=$P(aleg_sst_enable)
aleg_session_expires=$P(aleg_sst_expires)
aleg_minimum_timer=$P(aleg_sst_min_timer)
aleg_maximum_timer=$P(aleg_sst_max_timer)
aleg_session_refresh_method=$P(aleg_sst_refresh_method)
accept_501_reply=yes



Sems version:
1.4.3+spce2.8.3




Any hint?



cheers,

Jon
