We have setup of UCM6.1 > Cisco h323 gateway. We have LD PRI today off AT&T 4ess switch with the nsf-service megacom defined. Tonight AT&T is going to re-home PRI to 5ess switch.
In gateway config, there is not an option to define Megacom service for 5ess like there is for 4ess. I can define this in CCM under route pattern in the ISDN Network-Specific Facilities Information Element section.
Defining megacom service here, instead of under D channel, are their any issues? Does this pass Information Element along even when using h323 on gateway? Or do we have to switch to run MGCP in order for this to work with 5ESS?
