IOS MGCP Gateway configuration assistance

[daniel.kline]

I am trying to configure an MGCP gateway on a Cisco router to route externally originated calls to a non-Cisco Call Agent.

I will have four (POTS) phone lines entering the building that need to be routed through the IP network to the Call Agent for processing.

I assume the four PSTN lines are considered FXO lines and can be configured similar to the following example: http://www.cisco.com/en/US/partner/products/sw/voicesw/ps556/products_tech_note09186a008017787b.shtml.

The router I am hoping to use is a 3640 with an NM-HDA with 4FXS and 4FXO ports. At present, the router doesn't recognize the NM-HDA, but I think that is an IOS version issue.

Regards,

Daniel,

I have never connected to a non-Cisco Call Agent, but I assume the configuration is very similar to the information provide in the URL.

I would try the following commands on the gateway:

mgcp

mgcp call-agent service type mgcp version 0.1

mgcp dtmf-relay voip codec all mode out-of-band

mgcp modem passthrough voip mode nse

mgcp package-capability rtp-package

no mgcp timer receive-rtcp

mgcp sdp simple

mgcp fax t38 inhibit

mgcp bind control source-interface FastEthernet0/0

mgcp bind media source-interface FastEthernet0/0

dial-peer voice 1 pots

application MGCPAPP

port 1/0/0

dial-peer voice 2 pots

application MGCPAPP

port 1/0/1

dial-peer voice 3 pots

application MGCPAPP

port 1/0/2

dial-peer voice 4 pots

application MGCPAPP

port 1/0/3

You need the folowing software on the 3640 to support the card:

Cisco IOS Software Releases 12.2(2)XT, 12.2(8)T, 12.2(11)YT, 12.2(15)ZJ, 12.3(1), 12.3(2)T

The module requires Cisco IOS Software "Plus" feature set.

Let me know if this works.
