Can only receive 7 calls at a time on SIP

[Bivman]

I have an IP Office 500. I think the software is 4.0 (15)
I have 124 VCM channels. When I get a large call volume, usually Thursday nights, I can only register 7 calls and then I start getting congestion reports saying not enough VCM channels available. Any ideas?

Thanks,
-Jon

vcm 32 card will only give 30 vcm channels, seems to follow suite on the 64 vcm only giving 62 channels, don't know why.

TT
it has 32 or 64 channels if you are using g711, it only has 30 or 60 if you are using g729 codec and only 22 and 44 if you are using g723 codec. The more compressed the data is the less channels it lets you use for it

Thanks Westi, never knew that.

 

[Westi]

would you know that I ran across that info a few days back and thought that this is quite interesting and I should remember that for a rainy day (like today) and I have to make sure that you guys over the pond are not thinking that we over here are totally useless

Geez... I was about ready to unscrew my head and bounce it down the highway!!!!
I've been futsing with this thing all day....
I started fresh and ended up worn out...
WHAT a DIFFERENCE a single digit in an IP address makes!!!!!!!!!

It was the first IP I put in this morning... Didn't notice it till I finally started going thru everything bit by bit...
It was on the SIP line... I did that first so I wouldn't have to reboot the main number during the day... Did it wrong.... GEEZ!!!
Anyway, here's where I am on the trunk to trunk...
I can make calls just fine between the two places. BUT at the home office, I want to have the SIP number field have the main number or the number of the subdivision in there. In order to call the extension from CA, the extension number has to be in the SIP name field, otherwise the SIP trunk reports 404 not found. Is there another way around that?

Thanks,
-Jon

(Like maybe a number to alias table?)

Big test tonight guys... I traded VCM cards... Tried to get as many calls as I could flippin' through the switch, I made it up to 9 VCMs... So I'm ahead there... (Useta was only 7 worked.) We'll see when the big calls hit around 8:30PM CDT...
Had a 4-port copper trunk daughter card that I had to trade over during the switch... Now it's acting up. Port 1 (Line 9) will dial out once after a reboot, but then never again until another reboot. Lines 10-12 are all fine. Wonder if that confirms that the card the daughter card is sitting on, may be causing trouble? Line 9 works fine for incoming calls.

On a side note, is there a way to forward calls through a short code across a SIP?
I have a 3XXX short code that allows a caller here to call a 3xxx extension in our CA office. It works pretty slick (Especially after I spent a bazillion hours chasing a stupid IP address mistake....)
Now what I'd like to do is be able to take an outside incoming call, and send it down the SIP to an extension or group in CA. Forward to the shortcode doesn't work.. Is there an easy fix?

Thanks, (and I'll let you know what I find out about the VCMs later tonight...

-Jon

 

[Westi]

you can take a User and forward that user to the extension you actually want to call. That usually works. So forward it to 3456 (or what you need) and it should follow the 3xxx shortcode.
Line 9 problem: is your modem enabled on the first line? there is a checkmark in the line for it and take it off if you have it on.
Good luck tonight with your test and if you see 8 calls pick up the phone and make a few more ring in just to stress the system a bit more.

The modem switch is in the first line screen and is not checked. The only difference in any of the channels is line 9 is not checked for "Allow analog trunk to trunk connect"
Line 9 is it's own call group, while 10-12 are a group unto themselves.

Thanks,
-Jon

 

[Westi]

Kyle
do you mean the checkmark for the modem or the VCM channels?

Jon
the own line group does that mean that the line has it's own outgoing line ID?

[Bivman]

Yes, line 9 has it's own outgoing line ID. (It's my fire alarm line - doesn't THAT figure!!)

Well, the good news is, I saw at least 19 lines coming in at once on the SIP trunks, and there were no VCM congestion reports. The bad news is, the SIP provider didn't get the line switched over until most of the traffic had passed. Sigh...

But so far, the good outweighed the bad so I guess the VCM card swap told the story of why the switch was rejecting calls. Now I just need to convince the "service" guys that I need a new card. (And I bet the card that's making my line 9 go whacky is the faulty one!)

Thanks for all your help guys.

Hey Joe, I tried forwarding a user to the shortcode but it made the sound like the "waiting for a line" I can't remember what the trace said... Something about it matched the shortcode 3xxx and targeting, but it didn't make it across the SIP.

[Westi]

Jon
with it's own outoging line ID the line 9 will not get used outgoing axcept if you create a very "creative" ARS setup.
don't forward the user to the shortcode just forward it to a number starting with 3 so that it targets the other system.

I made a shortcode, *#7N that forces the call to ARS 54:Fire.
ARS 54 uses call group 4 for dialout. Line 9 is set for outbound group 4.
In any case, it was working fine, until I swapped VCM cards, and put the analog trunk daughter card on the other VCM card. Since then, line 9 will call out once, after a reboot, and no more. Every time I reboot, I can make one call on line 9, after that, I get a "waiting on line". It's like the call doesn't clear. (I suspect this is the VCM card that was only allowing 7 calls, and it has something to do with the hardware being goofey in the card.)
For now, I have switch the *#7N shortcode to send to ARS 53:Analog, and it shares the lines I have set aside for 911 and outgoing FAX calls that don't work on the SIP. Seems to be fine.

Thanks,
-Jon

Power down the ipo
Pull the VCM card with ATM
Powerup the ipo and remove the line
Power down and put the VCM card with ATM back in

This will auto generate the line again

Write down all setting to be sure !!!

I guess I can do that. But I'm still pretty sure I have a bad VCM card...
Does a firmware update, also update the cards?
(Although if the hardware on a card is bad, I'm not sure a firmware update would do any good anyway.)
Where are all of you guys anyway?
I saw a post about being "across the pond", and tlpeter has Chinese or something...
