Cannot dial out in Fallback mode

We are running CUCM and when we lose connection to CUCM, CM fallback is enabled. The rpoblem I am having is that the phones are allowing me to only dial 4 digits. We are using a h.323 gateway and everything works properly when connected to CUCM.

What am I missing? Thanks in advance.

Here is my config:

Cannot dial out in Fallback mode

Hi Jason,

Can you capture the following debugs for an outbound call in fallback mode:

debug voip ccapi inout

debug isdn q931

Looks like the gateway is matching the wrong dialpeer i.e. 1000 / 1001 voip dialpeers.  Do you have any reason for configuring destination-pattern as [1-9]...$? In other words, do you have any 9xxx patterns on your CUCM which someone dials from the PSTN world? If not, then I would change the destination pattern to something like [1-8]...$ to avoid the overlapping patterns.

HTH.

Regards,

Harmit.

Cannot dial out in Fallback mode

Thats exactly what it is doing.

Funny thing was that I went to go change the dial peers for 1000 and 1001 to what you suggested and removed the 9, now it works!!!

Thanks
