SRST / MGCP Failover Problem

Hi all


I am simulating a failure on our UC 6 system, and the IP Phones have successfully gone into CM Fallback Service Operating mode. However, when I dial a number, it only accepts 4 digits and then tries to set up the call.

Below is the config:


call-manager-fallback

max-conferences 8 gain -6

transfer-system full-consult

ip source-address 172.28.3.254 port 2000

max-ephones 300

max-dn 300

dialplan-pattern 1 011256.... extension-length 4

call-forward busy 9000

call-forward noan 9000 timeout 15

moh music-on-hold.au

multicast moh 239.1.1.1 port 16384


Is the dialplan-pattern config correct?

On the CUCM phones are configured with 4 digit extensions and have the 011256XXXX masked.

the dial plan dose not effect

this problem should be from a dial-peer

check your dial-peer

it sounds you have a dial peer that has destination pattren as 4 digits and get matched first


if didnt solved post you dial peers


good luck
