[OpenSIPS-Users] sst module killing calls

[Ronald Cepres]

Hi Bogdan,

I get a very similar behavior as what Jeff gets. I can see the re-INVITE
coming and I'm sure that it goes through loose_route block. I can also see
the "Update by a REQUEST" log. Here's a snippet of the logs after getting
the re-INVITE:

DBG:dialog:dlg_onroute: route param is '04e.1dc98a86' (len=12)
DBG:dialog:lookup_dlg: ref dlg 0x780a4fe0 with 1 -> 3
DBG:dialog:lookup_dlg: dialog id=1755880657 found on entry 3648
DBG:core:parse_headers: flags=48
DBG:core:parse_to_param: tag=9979
DBG:core:parse_to: end of header reached, state=29
DBG:core:parse_to: display={}, ruri={sip:NXXNXXXXXX at OPENSIPS.IP:5060}
DBG:dialog:next_state_dlg: dialog 0x780a4fe0 changed from state 4 to state
4, due event 8
DBG:dialog:dlg_onroute: sequential request successfully processed
(dst_leg=0)
DBG:dialog:get_dlg_timeout: invalid AVP value, use default timeout
DBG:dialog:dlg_update_cseq: dlg 0x780a4fe0[0]: cseq is 1
DBG:dialog:run_dlg_callbacks: dialog=0x780a4fe0, type=16
DBG:sst:sst_dialog_request_within_CB: Update by a REQUEST. INVITE
DBG:core:parse_headers: flags=ffffffffffffffff
7fcf80a53e41f75c431e5b7d0300c238 at OPENSIPS.IP: entering loose_route block..

Dialogs still expire after the timeout set by sst module. What else can I
check to see where might probably be wrong?

Thanks!

Regards,
Ronald
