Trunk to trunk joining on OXO

[hung.le]

Hi Everyone,
I have problem with analog trunk to trunk joining on oxo.
- my system has 02 analog trunk, all trunk routs incoming call direct to extension 100
- Extension 100 make Immediated call divert to an external number B
- When external number A makes incoming call to OXO system, it automatic divert calls to external number B --> 02 trunk lines in OXO are in used
- After external number A and B release call, 02 trunk lines in OXO system still maintain status "Busy", it is not auto release. so that another incoming call cannot go to OXO system

Does anyone has experience with this problem?
Pls share your experience with me.

thanks and best regards!

For analog line you have no "release" signal, just "busy" tone.
Manage "busy tone detection" in external line and adjust parameters if necessary.
