SRST Fallback Issue

[heathrw]

Hi,

Have the following configuration for SRST router with an E1

dial-peer voice 10 pots

incoming called-number .

direct-inward-dial

port 0/3/0:15

!

dial-peer voice 100 pots

destination-pattern 0T

port 0/3/0:15

!

dial-peer voice 2000 voip

preference 1

destination-pattern 777..

progress_ind setup enable 3

progress_ind progress enable 8

translate-outgoing calling 1

voice-class codec 10

voice-class h323 10

session target ipv4:172.16.x.x

dtmf-relay cisco-rtp h245-signal h245-alphanumeric

ip qos dscp cs5 media

no vad

!

dial-peer voice 2001 voip

preference 2

destination-pattern 777..

progress_ind setup enable 3

progress_ind progress enable 8

translate-outgoing calling 1

voice-class codec 10

voice-class h323 10

session target ipv4:172.16.x.y

dtmf-relay cisco-rtp h245-signal h245-alphanumeric

ip qos dscp cs5 media

no dial-peer outbound status-check pots

num-exp 08666777.. 777..

num-exp 8666777.. 777..

num-exp 666777.. 777..

!

!

call-manager-fallback

max-conferences 4 gain -6

timeouts interdigit 5

ip source-address 172.17.z.x port 2000

max-ephones 168

max-dn 168 dual-line

When the phones register with the SRST users can make outgoing calls but incomming calls do not work.

At what point when the number comes in via pots does it hand off to the CCM FallBack to match the registered extensions? It matches the VoIP Dial peers ok so is there a preference of them over the ccm fallback?

Thanks

Hi,

What are the SRST User extension numbers, how many digits long are they ?

It could simply be a num-exp problem.

Hi ,

In your Call-manager-fallback , you must set also the expression :

dialplan-pattern 1 8666777.. extension-length 5 no-reg

So that you can link the internal number with the external .

Hope that It will help you ....
