VG224 - Analog outbound dialing issue

Unanswered Question
Aug 22nd, 2008

I am running CCM 4

I have several VG224 services connecting my analog phones to the call manager.


One of my phones has a weird issue


Issue - When you pick up the receiver you hear dial tone. As soon as you press a button, it goes to a fast busy signal.



In the same room, there are 2 other vg224 connections. All 3 phones are configured the same (Partition and CSS).

The other two work fine.


I can call from an outside line and it rings fine and can be answered. I can setup call FNA or FA on its ext and it routes properly (Par and CSS are set correctly).


I cannot figure it out. I want to say it's a wiring problem or that port on the VG might be bad.


I already reset the VG and all the other phones on this VG work. There is an open port I can attempt to move it too.


I was wonder if anyone has seen this issue before? If so, am I going in the right direction thinking it's a physical issue.


Should I repunch the lines and if that fails, move it to the other port.

Hi Donald,


It kind of sounds like a bad port if the CSS is the same as the working phones. If you get dial tone and can ring the phone I would think that the wiring is OK. If you are re-punching the line, then try to flip/reverse Tip and Ring just in case the Analog phone you are using is polarity sensitive.


Switching ports is probably the "quick fix" :)


Hope this helps!

THanks


Thats what I was thinking. I mean I cannot make any more changes to the CCM. We only have 2 partitions and several CSS.


I will try that

Thanks again

Hi D0nprintup,


We already experienced this kind of issue. Sometimes, you have to launch a reset of the MGCP config from the CallManager side. You have to call Reset from GW config page or by resetting GW's endpoints.


I don't know why it happens. Do you experienced this issue again?

Greetings


I forgot to update this. I found out what the problem was.


I logged into the CLI of the VG and after a sh run. I noticed there was a werid setting (Static information) for that port. When I removed the port out of call manager and did a show run again, it was still on the VG. I removed the information from the VG. Then I added it back in via the webpage and did a sh run on the gateway to verify it added it correctly. Now it all works.


Next time I know to check the CLI

Thank you for your reply.


Your issue is strange indeed... It is not the first time we experience "strange" problems with a VG224 and/or MGCP.


Sometimes the config on VG/GW is not refreshed correctly, sometimes ports are not registered until the next "no mgcp/mgcp", sometimes they are registered to the wrong node not according to the CUCM group order...


We are looking for changing our signaling protocols to MGCP-->SCCP for VG224 and MGCP-->H323, but when the dialing plan is complex, H323 is a pain in the a..!


Good luck :)
