SV9100, one particular IP phone keeps disappearing
SV9100, one particular IP phone keeps disappearing
(OP)
We've got an SV9100 CP10 in one of our customers' sites. They have a number of Ascom i62 wireless handsets which are just set up as generic SIP extensions. Most of them work but one phone in particular keeps dropping off the system. I go into Filter Options, then IP Phone List and make sure that the extension for that phone is selected. I see the extension appear under IP* on the Blades page. I take a download from the system and I see that the extension has appeared on the list of IP phones and disappeared from IP*, which is great. I can see the phone details under SIP Terminal Settings. But a few moments later I take another download from the system and the phone has gone again. I can repeat the process but the same just keeps happening.
I suspect that there may possibly be a license issue of some kind - is anybody able to confirm please if a license shortage would cause the behaviour I've described?
Thanks!

@OzzieGeorge - No IP address clash that I can see. The handset continues to respond to ping and I can browse to it so I know it's the correct handset on the correct IP address.
I took a packet trace from the SV9100 and it would appear that the handset is continuously trying to register with the NEC, but the NEC is rejecting it. Please see the snippet below:
If it was a licensing issue, would the NEC be rejecting the phone as we see in the snip, above?
So, here are the details for the licenses which I have obtained from Feature Activation within PCPro:
0300 System Port x 251
5101 DT IP Terminal x 25
5103 VoIP Channel x 44 (Blade License Setup says 36 and reverts to 36 if I change it to 44)
5111 IP Terminal x 9
5201 Mobile Extension x 4
7101 Extensions x 512
And here is a screenshot of part of the Blades page in PCPro, showing ports in use etc:
In the image above we see ext 5054 sat waiting to register with the NEC. A few moments after the screenshot was taken, it moved from IP* to IP. After a few seconds more, it once again disappeared.
The licensing numbers never seem like they add up, to me. I mean, the screenshot suggests that 278 ports are in use. But system port license quantity is only 251 according to Feature Activation. So there's a shortfall of 27 system port licenses if I read it correctly. But why then are there not 27 extensions that aren't working? Why would it affect only one phone? I don't understand.
Any further suggestions would be great if you don't mind taking a look at the license quantities etc, please.
Thanks!
Ps - Please let me know if you can't read the numbers in the screenshots. I thought it would be possible to click on them in the post and view them full size but that doesn't seem to work for me.
RE: SV9100, one particular IP phone keeps disappearing
Just a thought on this.....
I have experienced in the past that if IP phones were not deleted from the system properly, the system will keep a license allocated to it even though the phone no longer exists on the system.
The feature activation will not properly reflect the available license count when this occurs.
How many IP phones are currently registered to the system? 36?
RE: SV9100, one particular IP phone keeps disappearing
And, for my edification, what are S-Point trunks used for? We don't use them in our area.

And here's one of the port quantities which I've truncated so it's not massive:
Info from Feature Activation which I think is relevant is as follows:
0300 System Port x 251
5101 DT IP Terminal x 25
5103 VoIP Channel x 44 (Blade License Setup says 36 and reverts to 36 if I change it to 44)
5111 IP Terminal x 9
5201 Mobile Extension x 4
7101 Extensions x 512

And in answer to OldNECguy's request, here is what's in 10-54:
If there is anything else I can get which might help, please let me know.

When is the last time you generated a lic files for updated firmware?
RE: SV9100, one particular IP phone keeps disappearing
RE: SV9100, one particular IP phone keeps disappearing
The S-Point and T-Point are the licenses used for Loopbacks, or so I believe.
RE: SV9100, one particular IP phone keeps disappearing
@OzzieGeorge Thanks for that information. I wasn't aware of that. I'll take a look at the extension ranges. Is it as easy as deleting the existing VoIP extension using WebPro and then setting it up again in one of the gaps in the VoIP extension range? I think one of those gaps is probably the extension I'm trying to get working.
Thanks
