Please help. Having trouble trying to configure a MGCP gateway on CUCM 7.0 for the first time. I've added the 2821 router as an MGCP gateway and have selected Slot 0. When I try to save the subunits it fails with a blank screen and no subunits are added.
My 2821 includes:
SubSlot 0: HWIC-4T (4 x serial)
SubSlot 1: VWIC2-2MFT-T1/E1 (2 x E1)
SubSlot 2: HWIC-4B-S/T (4 x BRI)
SubSlot 3: VIC3-2FXS/DID (2 x FXS)
SubSlot 4: PVDM2-32 (DSP's)
1. Is it valid to have these cards installed together? They show up fine on the router.
2. The serial module is not available in the dropdown list on CUCM - should I leave this as <None>?
3. The HWIC-4B-S/T is not available either. How can I add support for this?
4. Initially I only want to configure the E1 link. Do I have to remove the other interface cards?
Sorry if this is an simple question, I have searched other forums without success. If you need any more info, please let me know.
No maybe about it I'm afraid.
Look at your other cards:
HWIC-4T - HWIC=High-Speed WAN Interface Card
VWIC2-2MFT-T1/E1 - VWIC=Voice/WAN Interface Card
VIC3-2FXS/DID - VIC=Voice Interface Card
My advice would be don't trust what dodgy resellers say about the cards - always check the product documentation on Cisco.com. The Data Sheet for this card is at this URL and is titled 'Cisco 4-Port ISDN BRI S/T High-Speed WAN Interface Card'
There is no BRI card that supports both voice and data from Cisco unfortunately; I know this seems odd (trips us all up when we're starting out in this technology) but I'm sure there are good reasons for it...
Cisco support won't be able to tell you much more than this; other than the cards you should be looking at would be a VIC2-2BRI-NT/TE (2 BRI ports = 4 channels) .. or if you need more port density there is a high density option which includes FXS ports on an NM that can have two 4-port BRI daughtercards added to it:
