Mobile calls forwarded by asterisk trunk aren't accepted by TDE

[digiteltlc]

This is driving me crazy

Provider sip trunk ---- asterisk ---- sip trunk ---- TDE600 ---- ISDN

Calls from provider sip trunk come to asterisk extension
That extension is forwarded to an outside number (it doesn't matter destination is fixed or mobile number) via a sip trunk to TDE600 that uses BRI interface to place outside calls.

All is working fine if the caller is a fixed line (CLI beginning with 0xx)
Forwarded calls are refused by TDE if caller is a mobile one (CLI beginning with 3xx)

Asterisk trace of sip trunk to TDE is IDENTICAL in both case until TDE joins channel :

-- Called PJSIP/<outside_destination_no>@TDE600

Fixed line caller :

-- Channel PJSIP/TDE600-00000fda joined 'simple_bridge' basic-bridge <29c92ef7-7df9-44f1-8f53-42098f03a725>
> 0x7fbc700b9050 -- Strict RTP switching to RTP target address 192.168.100.2:12190 as source
> 0x7fbc480aa810 -- Strict RTP learning complete - Locking on source address 192.168.100.2:12186
> 0x7fbc700b9050 -- Strict RTP learning complete - Locking on source address 192.168.100.2:12190
Call takes place via ISDN

Mobile caller :

-- Channel PJSIP/TDE600-00000fd4 joined 'simple_bridge' basic-bridge <927da8ef-89f0-48b5-88d4-d64084d10edb>
> 0x7fbc700b9050 -- Strict RTP switching to RTP target address 192.168.100.2:12166 as source
-- Channel PJSIP/TDE600-00000fd5 left 'simple_bridge' basic-bridge <093f3a80-9417-4909-8578-9f90ba86e477>
-- PJSIP/TDE600-00000fd5 Internal Gosub(app-missedcall-hangup,TDE600,1) start
Call is immediately ended

I can't figure out why or what on TDE side refuses a call to be forwarded to BRI when CLI is starting with 3

Any idea ?
Thanks

Is TDE trying to place this call (from mobile) to the BRI trunk?

Can you clarify on this part That extension is forwarded to an outside number (it doesn't matter destination is fixed or mobile number) via a sip trunk to TDE600 ?
