t_suspend and t_continue in tm module

by Richard Good

Hi We are using the t_suspend and t_continue functionality to asynchronously send Diameter messages. This works nicely when we suspend and resume on a SIP request. However in some circumstances we want to send a Diameter message on a SIP response. I have found that the SIP responses continue to be relayed despite being suspended and returning 0 to the cfg file. I am investigating the cause but before I get any deeper does anyone know if the t_suspend and t_continue functionality in the tm module can be used on a SIP response? Regards Richard.

[tracker] Comment added: Entity URI in NOTIFY XML body

by sip-router

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#324 - Entity URI in NOTIFY XML body User who did this - Daniel-Constantin Mierla (miconda) ---------- OK. It may make no sense to have a module parameter if using uri schema is the correct mode. Also will be all with or without schema, so won't work in mixed environment. If proved not to work with some UA, then we'll have to add some flags to mark each subscription. The condition will be in config file based on UA or what so ever test. Hopefully will not be the case. I'll ping the author of the module for an opinion as well. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=324#comment999 You are receiving this message because you have requested it from the Flyspray bugtracking system.
