MGCP Gateways and CUCM 8.6

[antonio.vazquez]

Hi,

I'm performing a migration from 5.1 to 8.6. Our customer has several MGCP gateways connected  against the CCM. IOS from gateways are 12.4.

My question is, could we have problems between MGCP gateways and CCM 8.6 due an incompatibility between IOS version and CCM?

Hi,

Can you try a pots phone on the FXS port rather than the fax and prove if the issue

is to the port or the FAX
