[asterisk-users] Passing video calls / bearer capability thru PRI
Hi all,
using latest asterisk-svn
I want to reflect an video call incoming via an PRI EuroISDN channel to
another outgoing PRI channel,
and I want the the outgoing channel to have the exact same bearer
capability
< Bearer Capability (len= 5) [ Ext: 1 Q.931 Std: 0 Info transfer
capability: Unrestricted digital information (8)
< Ext: 1 Trans mode/rate: 64kbps,
circuit-mode (16)
< Ext: 1 User information layer 1: G.7xx
384k Video (38)
unfortunately using a simple extension like
exten => 445,1,Dial(${TRUNK}/04109555502)
it is truncted to
> Bearer Capability (len= 4) [ Ext: 1 Q.931 Std: 0 Info transfer
capability: Unrestricted digital information (8)> Ext: 1 Trans mode/rate: 64kbps,
circuit-mode (16)> Ext: 0 User information layer 1: Unknown
(24)
Where may I adjust/jump in to have the Ext: 1 User information layer 1
passed thru unmodified ??
TIA for any hints,
Bruno
