SRST Setup

tahequivoice · ‎03-31-2005

I have been searching for a consice setup guide start to finish to setup an SRST router with Callmanager 4.0. I am having confusion as to what software to load onto the router. I have a fully functional CME/CUE router, but dont want to use that, I am planning to use 1760 and 2801 routers for SRST. Also, how do these work when the T1 to them goes down? FXO cards and land lines?

FIrst off you should use the CallManager Compatability Matrix to help you chose an IOS version that has been tested with you CCM, think of these as MIN tested version:

http://www.cisco.com/univercd/cc/td/doc/product/voice/c_callmg/ccmcomp.htm

If you SRST router is also a registerd MGCP GW with the CCM you can use MGCP fallback in the event that the router can not communicate with the CCM it will use configured dial-peers to route calls out the local GW. If the SRST is also configured as an h.323 GW the then all devices registerd in SRST will you the dial-peers to route the calsl when in SRST or not.

Here is what I have done so far.

http://www.cisco.com/univercd/cc/td/doc/product/voice/srst/srst33/srs33spc.htm

Found the loads listed, of course nothing is documented as to what should be done with these files, but that is another story.

Followed this guide;

http://www.cisco.com/univercd/cc/td/doc/product/voice/srst/srst33/srst33ad/index.htm

Got to the part where you put in the application, call application appname location etc. in config mode, command does not exist.

Call-manager-fallback appears to be working on the router, phones do not register. I have the phone loads on the flash;

SRST#dir flash:

Other than the 7970 phone load, which I could not locate the other loads are what where specified in the matrix. We are running 4.02a, the router is a registered MGCP gateway, it has a WIC-1ENET in slot 0 and a VIC-2FXO in slot 3, 3/0 is currently configured with a pots line and registered. The phone shows the correct address for the SRST as well in its network settings.

I attached the sh ver and sh conf.

I would try app note at

http://www.cisco.com/en/US/tech/tk652/tk701/technologies_configuration_example09186a008012ecc6.shtml

This worked fine for using SRST for FXO ports.

my config was

What version IOS are you running? The version that is recommended in the Doc no longer has application mgcpapp, instead it is service mgcpapp.

Something that was very strange has happened as well. When I have the phone line connected to the FXO port, the phone I have connected was getting a call every 15 seconds. I rang constanatly and when my wife tried to make a call to me at work to tell me she never got my voice mail, it kept ringing, and I had a voice mail message that was nothing but a phone ringing. DO you think it has something to do with how I have it setup?
