[cisco-voip] H323 vs MGCP

[Davis, Michael]

Also, fractional T1/E1 circuits are not supported with MGCP - though you can work around this by placing the unused B-channels in maintence mode (CCM Advanced Service Parameters) for up to five circuits.
 
Here's a nice link outlining some of the feature and hardware support diffs:

	Russell,
	Check check very carefully what is and is not supported on the MGCP and 2801..
	There are some VWIC combo's that require H323 on the 2801 with CCM...

	Hi Bill
	 
	Thank you so much for your answer!  I just want to be clear on this - if I use H323, I'm not hurting anything, but I get better monitoring with MGCP.  The reason I'm asking is this:
	 
	We had an H323 enabled before and everything seemed to be working properly.  I enabled MGCP and now nothing works - the calls just get kicked back to the operator at the remote location.  I think this might be a configuration issue with the remote PBX, but I can't be sure.
	 
	Thanks
	 
	Russ

	Usually more feature available with H323 (CallerID), but MGCP is managed via CallManager.  Because CCM manages calls to the MGCP gateway, you get better monitoring statistics (current # of Calls, channels in use, etc.).
	 
	My rule of thumb is, use MGCP when you can, H323 when you have to.

		Hi everyone 

		I'm in the process of setting up a CCM (4.1) and 2801s.  What is the advantage/ disadvantage between using a trunk between the CCM and the 2801 (uses MGCP) and a regular H323 gateway?

		Thanks
