Inter extension dial timeout

Good afternoon,

We have installed FreePBX 2.11 with latest module upgrades + asterisk 13. (basically it was installed from your ISO : SHMZ release 6.5 (Final))

Issue we are facing now is that dial timeout for extensions which are in the ring group being set by dialparties.agi to 2 seconds by some reason

For example, we have an extension 5000 (in ring group), 5009 (not in ring group).

Call from 5000 to 5009 take ring timer and works fine, but call from 5009 to 5000 is with 2 seconds timeout instead of default value of 20:

-- Executing [s@macro-dial:7] Dial("SIP/5201-000046ec", "SIP/5000,2,TtrIM(auto-blkvm)") in new stack

== Using SIP RTP TOS bits 184
== Using SIP RTP CoS mark 5
– Called SIP/5000
– Connected line update to SIP/5201-000046ec prevented.
– SIP/5000-000046ed is ringing
– Nobody picked up in 2000 ms

SIP/5000,2,TtrIM(auto-blkvm) … 2 seconds is a ring time while default is 20.

Change to extension ring time or global have no effect.

Can somebody help us to fix that issue? Is it a bug or we just did something wrong?
