Voip Over GRE (one site behind an ASA Firewall)

Greetings to all.

i had a problem to establish a voip session between 2 sites as despicted on picture.image001.jpg

on site left, i had an 2851 ISR Router with running call manager express, in the other side of the tunnel gre i had an 2801 isr with fxo and fxs ports.

when i try to make a call with a phone or csim between sites i had connection attemps but no voip call is established.

i'll face several problems like Disconnect Cause=49, and others and i'll fixed with RSVP and other documents i'll found on cisco support site.

currently i don't know where to shoot to fix the problem.

note that some stuff are incomplette, because i'll need to go thru pstn on right side via PRI E1 interface, currently i'm using an FXO for testing prurposes

i'll attach the configurations of right, left, and right switch

after running debugs i capture them and attach'd as left-debug and right-debug.

i'll put those on both left and right routers.

debug cch323 session

debug cch323 function

debug cch323 error

debug ras

debug voice dialpeer inout

debug voice dialpeer function

debug voice dialpeer error

debug h225 asn1

debug h245 asn1

debug voip ccapi inout

i know the call voip fails, because after a 20 to 30 seconds, the call goes thru fxo port 0/1/0 on right side.

thanks for your time.

had a great day . best regards, and rate if you'll find this post useful
