I have TB1 and TB2. I’m trying to get an incoming POTS call on TB2 to go to TB1. I have the trunks, outgoing routing and all the other stuff working. I set a misc destination on TB2 to dial TB1 ext 8100. It works. But when you call the POTS line the transfer happens, I can hear the receptionist but they don’t hear me. One way audio!

Now my TB1 is 2.2.4 and FreePBX is 2.3. in the trunk settings I WANT
disallow=all
allow=gsm
context=from-internal
host=192.168.17.100
jitterbuffer=yes
qualify=yes
secret=****
trunk=yes
trunktimestamps=yes
type=peer
username=trixbox1user
auth=md5
encryption=aes128

but when I apply the settings, I get it re-ordered, by freepbx as
allow=gsm
auth=md5
context=from-internal
disallow=all
encryption=aes128
host=192.168.17.100
jitterbuffer=yes
qualify=yes
secret=****
trunk=yes
trunktimestamps=yes
type=peer
username=trixbox1user

then in the iax_additional.conf I get this
username=trixbox1user
type=peer
trunktimestamps=yes
trunk=yes
secret=****
qualify=yes
jitterbuffer=yes
host=192.168.17.100
encryption=aes128
disallow=all
context=from-internal
auth=md5
allow=gsm

The only thing I can see is the re-ordering of disallow=all and allow=gsm? I have another server with the same trunk settings and all works great. Anyone have any ideas? Thanks for your time and help. And yes I have IPSEC VPNs between my sites.
