Hi Sankar,

Thanks a lot for your elaborate config with explanation. I will try this and let you know the results by tomorrow. I have one more query. I installed the VG224 as mgcp gateway and configured a analog phone. I was receiving the dial tone in the phone but when i tried dialing to other ip PHones i was not able to. Is there any specific config we need to do in vg224 for this to happen.

Is the port registered to callmanager ? do a sh mgcp endpoint.

Did you configure the DN for this phone in Callmanager under the gateway-> port. If yes, check the calling search space on the VG224 port configuration in callmanager to see if that has access to the partition in which other ip phones are.

Sankar,

The ports got registeed to callmanager. CSS is also fine. When i call from the IP Phone to the Analog phone i can hear the phone ringing tone in the ip phone but actually the Analog phone is not ringing.

Then i tried with SCCP instead of MGCP in vg224. This time i can able to call from ip phone to analog. But the reverse is not working.

Krishna.

Krishna,

Try this.

no mgcp,

wait 5 seconds,

mgcp,

make sure after this, the port gets registered and then try placing a call from analog device to ip phone. What do you here when you pick up the handset and dial an ip phone's extension ?

Sankar,

When i lift the analog phone handset i will hear dial tone but when i dial the first digit of the number i will get a busy tone.

I will reconfigure it as MGCP and try your solution.

Krishna.

Krishna,

It does not matter for an analog phone, how you configure it as MGCP or SCCP or H323. All will work.

For fax and modems, its preferred to use MGCP or H323.

Sankar,

If you use MGCP is it still possible to use SRST for failover?

Sankar,

I had configured the vg224 as the mgcp gateway. Ports got registerd. when i lift the handset of the anlog phone i can able to hear the dial tone but not able to dial any other number. while dialing the number itself it gives a busy tone.

also did the no mgcp and mgcp config. No luck.

Krishna

Krishna,

This tells me that the issue is not the gateway but possibly the CSS or PT configurations. What number are you dialing first to hear the busy signal?

Do you use a prefix digit to access the trunks? Have you looked at your Call Manager route plan to make sure there are no issues there. Apparently the gateway or call manager think that the number is not in the route plan and are giving you a reorder tone.

I would look there.

Hi Sankar,

At last it worked. Thanks a lot for your help. Config is not the issue. The issue is in the krone patching. The port where the fax is connected was having issues. I enabled another port and in that it was working fine.

Thanks a lot.
