We have an issue at one of our locations .
Whenever there is call being forwarded to an outside cell phone number from turret phone at one of our location it doesn’t work. (for caller) Call disconnect after almost 1 minutes of Silence. (For final called pary) his phone rings for just second and disconnect and process repeats and lasts about 1 minute.
As per gateway debugs, we see a setup being received.

Then CM sends call setup to turret through another gateway.

Same gatway then receives setup back for the forwarded call (hairpin)

For which we receive a progress ind from telco.

We receive no message for next 10 seconds.
After 10 seconds the call originating telco disconnects the call.
040953: *Dec 15 22:11:03.306 UTC: ISDN Se0/0/0:23 Q931: RX <- DISCONNECT pd = 8 callref = 0x0F4A
Cause i = 0x80E6 - Recovery on timer expiry
collected traces for successful call hoever in that call telco doesn’t send call proc in response to set. It sends alerting.
In both good and bad call case call is going out through same circuit. That is 0/0/1 of srst gateway of the location.
Can somebody guide on this.
