[SR-Users] Dialog - timeout for dlg with CallID

[Daniel-Constantin Mierla]

Hello,

that confirms my guessing -- the ack was not handled in the dialog
context, the state 3 is defined inside dlg_hash.h by:

#define DLG_STATE_CONFIRMED_NA 3 /*!< confirmed dialog without a ACK yet */

Do you see any error messages in the logs when handling the ACK in the
config? Did you grab the pcap with sip traffic for such a call?

Try also to explicitly execute dlg_manage() for ACK within dialog.

Cheers,
Daniel
