SRST help

[calladd03]

    Hi guys,

I'll need some help configuring SRST.

I've set the call-manager-fallback command like this:

call-manager-fallback
secondary-dialtone 9
max-conferences 12 gain -6
transfer-system full-consult
ip source-address 10.10.0.2 port 2000
max-ephones 300
max-dn 500
system message primary SRST Fallback Active
system message secondary SRST Fallback
dialplan-pattern 1 04222..... extension-length 5

I can talk between DN but I can't get call outside.

I have a PRI link

Is there anything else that I have to configure ?

Thanks

you must configure a pots dial peer for outgoing call

example:

dial-peer voice 1 pots

desc outgoing SRST

destination-pattern 9T

port 0/0/0:15

[calladd03]

I configured it but still not working.

dial-peer voice 11 pots
destination-pattern 9T
direct-inward-dial
port 0/3/1:15
forward-digits all

what say

debug isdn q931

if you dial a number to PSTN?

[calladd03]

i've set the debug but nothing happens when I try to call.

I solved it. The port setting was not right.

Thanks

Hi Alex,

Well, the serial port that I specified was wrong. I checked the router and set the correct port.

Please put your config here maybe I can help.
