</div></div><p class="MsoNormal"></p><div><div class="h5">Hello,<br>
<br>
we are using the TM Module* t_suspend *function in our kamailio to suspend<br>
transactions (mainly INVITE requests). We do this as we send some push<br>
notification to the callee that will force it to re-REGISTER. Once we get<br>
the REGISTER, we resume the transaction with a *t_continue()*.<br>
<br>
If the callee never re-REGISTER, the FR Timer will terminate the INVITE<br>
transaction.<br>
<br>
This is working fine for us when the callee has a phone that can receive the<br>
push notification.<br>
<br>
<br>
Now, we want to be able to contact users having multiple devices: phone and<br>
desktop VoIP clients. The problem with current implementation is that if we<br>
wait for the re-REGISTER from the mobile phone, we may never send the INVITE<br>
to the desktop VoIP client if the mobile phone is shutdown.<br>
<br>
So, I'd like to now if it is possible to set a timer to the t_suspend<br>
command which will automatically resume the suspended transaction (without<br>
issuing an ERROR like the FR timer is doing)? I didn't see such possibility<br>
in the TM module, but is there another way to implement this?<br>
<br>
Hope I was clear enough<br>
<br>
<br>
Regards<br>
