mgcp and vg200 problems

I have two vg200's running 122-8.5T with NM-HDV-2T1 and a ccm running 3.2. I've had the gateways set up as H323 and things were working fine. Over the Christmas break I thought I would try MGCP on the vg200's and see how it worked. Everything seemed fine till school started back. Now I'm seeing lines locking up and when I do a "show voice call summary" I see EM_RLS_WAIT_RLS_REQ. I have one T1 going to a PBX and three going to the PSTN, and I'm getting this on all 4 T1s. I haven't found anything here or on CCO similar to this. Should I start changing timeout values or just go back to H323?

Thanks

Mark

Re: mgcp and vg200 problems

You could try to adjust the timeout values to see if that fixes the problem. Look over this URL that has some useful information on it as well. http://www.cisco.com/warp/public/788/AVVID/cm_mgcp_intro.html

Re: mgcp and vg200 problems

I went back to H.323, I didn't have time to play with it before the students got back. Thanks
