I am trying to configure cme in fallback mode. The phones register ok in srst mode but i am unable to make any outgoing calls or receive ddi calls on my Pri.


My DDI range is 8460-8479 & for testing I am trying to get ext 8460 to ring on an ephone-dn of 3306


Can anyone help and tell me if there is something wrong or missing with my dial peers or config?

"sh isdn status" has multiple frame establish


assume yes above, "debug isdn q931" on incoming call shows setup, and then connect?


csim start 84?? allows you to dial ip phone


csim start 9localdial or 9longdistance allows you to ring those local or long distance numbers

Hello,

in the Documentation (Configuring SRST Fallback Support), it says you shoud configure


srst mode auto-provision none


non

Does not include information for learned

ephones or learned ephone-dns in the running

configuration. Use this keyword when you want

Cisco Unified CME to provide SRST fallback services for Cisco Unified Communications Manager.


Mabye try this.


Bye

Drop the voice tranlation rule and try doing something like this. I have an office setup with CME fall back and found this to be easier

Thanks for all your responses.


I have actually managed to get this working, it turns out that my config was ok The problem was the way were testing the srst failover. The access lists we were using were only blocking communications between the phones & and CM whereas the Pri mgcp gateway was still able to communicate with the CM. As soon as I completely disconnected the WAN link I was able to make incoming outgoing calls on the pri in srst mode.
