Hi
Elastix1 --- R1(2821)-------R2(2911) ---------- Elastix2
In my scenario ,routers and Elastixs communicate with each other via the
codec g711alaw and two routers g729.

When fax send from Elastix1 ,R1 cant pass it to R2.
R1:

voice service voip
 allow-connections sip to sip
 fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
!
voice class codec 1
 codec preference 2 g711alaw
!
interface GigabitEthernet0/0
 ip address 192.168.0.234 255.255.255.0
 duplex auto
 speed auto
!
dial-peer voice 1 voip
description for Elastix
 destination-pattern 95511.+
 modem passthrough nse codec g711alaw
 voice-class codec 1
 session protocol sipv2
 session target ipv4:192.168.0.232
!
dial-peer voice 2 voip
description for R2
 destination-pattern 95515.+
 modem passthrough nse codec g711alaw
 session protocol sipv2
 session target ipv4:192.168.0.228
!
R2 configuration is similar to R1.

gold of this scenario : calls pass by codec g729 and fax by codec g711
i need true cisco configuration for pass fax from dial-peer with g729 codec
.
thank you
