Hello, I try to set the "fr_inv_timer" dynamically from DB. Under 60s it works fine. But I can't set more than 60s. Here are the TM parameters: # ----- tm params ----- # auto-discard branches from previous serial forking leg modparam("tm", "failure_reply_mode", 3) # default retransmission timeout: 30sec modparam("tm", "fr_timer", 5000) # default invite retransmission timeout after 1xx: 120sec modparam("tm", "fr_inv_timer", 60000) Here are the instructions to set dynamically: avp_db_load("$ruri/username", "$avp(s:inv_timeout)/usr_timeout"); t_set_fr($avp(s:inv_timeout)*1000); Is there anything wrong? Regards, Igor.
