[asterisk-ss7] chan_ss7 mtp3d

Sat Apr 30 22:21:03 CDT 2011

Hi.

you could configure two different ports for  signaling link, for example siuc1 port 12000 and siuc2 port 12001.

I hope this information are useful

bye

Hi
Could someone provide paid support for configuration of mtp3d and chan_ss7 for 100 E1 of which 2 are signaling links. The E1 lines are spread over 7 boxes ?

Thanks. 
Description of the problem I am facing is given below. 
Cheers!Anita.

Hi

I am running a massive 100 E1 lines over SS7, distributed over 7 boxes with
only 2 signaling links.

I am trying to get mtp3d and chan_ss7 work for 2 signaling links across 7
boxes.

When I run mtp3d, I get this

debian:~# mtp3d

debian:~# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere            tcp spt:12000
state ESTABLISHED
ACCEPT     udp  --  anywhere             anywhere            udp spt:12000

state ESTABLISHED

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Here it can be seen that both udp and tcp are open on port 1200. However,

nmap thinks otherwise

PORT      STATE  SERVICE VERSION
12000/tcp closed cce4x

Any pointers will be helpful.

Thanks,
Anita.
