I have CUCM 6.x and a MGCP gateway with SRST and several FXS ports with analog phones hanging off.
I want the analog phones always registered to the SRST gateway rather than CUCM because in the event of a problem with CUCM, I do not want to wait for SRST to kick in. In other words, I want SRST working ahead of time for the analog phones.
I know if these were IP phones, I could block 2000 permanently, or something like that to force SRST, but I don't know how to force the analog phones to register with SRST.
My alternative is to use the voice gateway as CME rather than MGCP w/SRST, but I would really like to stay away from CME due to some of the other complexity's of this voice gateway.
