MGCP in IOS question

[sparkymark]

I'm trying to set up a VIC-2FXS on a 1760 using MGCP and the documentation I'm following tells me to enter "ccm-manager config server <ip addr>" in global configuration. However when I attempt I get an invalid input marker at the second "c" in the command. Entering "cc?" gives me an "Unrecognized command" message. IOS version on this router is "C1700 Software (C1700-IPVOICE-M), Version 12.3(22)". Thanks in advance for any help.

This is typically happens when the software feature you are trying to configure is not support in the stream or release of IOS you have installed.

According to software advisor it would seem that the Latest IOS IPVoice release which supports the MGCP Gateway Control for the 1760 is 12.3(24).

This IOS release requires 64Mb Dram and 16Mb Flash.

I was thinking something like that, but now I have c1700-ipvoice-mz.123-24.bin loaded and still no ccm-manager command.

I've successfully entered MGCP commands:

"mgcp"

"mgcp bind control source-interface Lo0" and

"mgcp bind media source-interface Lo0"

so it appears mgcp is supported.

FYI I have one PVDM-256K-4 installed and "show voice dsp" shows the two ports on the fxs card are being serviced by the pvdm.

Mark,

Is there any chance you can post show version here please.

Then:

1. show isdn status

2. show ccm-manager <- if the router lets you that is

3. show ccm-manager backhaul <- if configured

4. show mgcp endpoint

Check out these documents:

<http://www.cisco.com/en/US/tech/tk1077/technologies_configuration_example09186a00801ad22f.shtml>

and

<http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123cgcr/vvfax_c/callc_c/ccm_c/int_bri.htm>

and the following commands from this document:

Configuring the BRI Interface as an MGCP-BRI Backhaul Endpoint

Also, taken from the following document:

ccm-manager mgcp 12.2(11)YU - This command was implemented on the Cisco 1760 gateway.

Bit of reading to do but do get back to us won't you.

Although MGCP is supported in IP Voice main IOS Train 12.3(34), MGCP Gateway support for CallManager is actually supported in ED release 12.3(14)T7 not main-line, with the exception of only 12.3(11)YZ2 and 12.3(11)XL1.

Unfortunately the minimum amount of DRAM required for 12.3(14)T7 and 12.3(11)YZ2 is 96Mb and 32Mb Flash. 12.3(11)XL1 requires 128Mb DRAM and 64Mb Flash. I would be inclind to opt for the T train release.

MGCP Gateway support for CallManager is also support in the following 12.4 releases:

12.4(6)XT, 12.4(4)XC7, 12.4(2)XA, and 12.4(15)T1 all which require 128Mb DRAM and 32Mb Flash, whereas the mainline train 12.4(17) requires only 96Mb DRAM and 32Mb Flash.

Thank you Allan for digging in to the version specifics on this, I chose 12.3(14)T7 and that did the trick.

Thanks to everyone for your assistance,
