iam sorry for 1700 config already erased...but

it's only analog phone at fxs and have dialpeer to sccp router..

---------------------------------------------

firewall has been fully opened between this all devices(scpp phone and 2 two router)...

is there easy guidance for this scenario(sccp and h323 router? Tx...

Hi,

if you have one-way audio and a FW in between, be assured the latter is the cause of the problem.

If cannot configure the FW to allow voice, what you can do set-up and GRE tunnel on your router. this way all your traffic will flow withing one single port. On the FW, permit IP protocol 47 (GRE). On the routers:

interface tunnel 0

ip address

tunnel source

tunnel destination

then configure all voip to use tunnel addresses.

Hope this helps, if so please rate post!
