Phone in Fallback mode... Available line 0 ???

Hi,

I have an issue with the SRST on a remote site. We had a network failure, and here is the "show ephone registered" during Fallback mode:

ephone-5[4] Mac:0024.142D.46DD TCP socket:[2] activeLine:0 REGISTERED in SCCP ver 15/9
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8
IP:10.247.230.66 51293 7941  keepalive 5 max_line 2 available_line 2
button 1: dn 2  number 5124  CM Fallback CH1   IDLE
Preferred Codec: g711ulaw

ephone-6[5] Mac:0021.A085.5373 TCP socket:[8] activeLine:0 REGISTERED in SCCP ver 15/9
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:8
IP:10.247.230.65 51777 7961  keepalive 25 max_line 1 available_line 0
Preferred Codec: g711ulaw

As you can see, ephone 5 and 6 are "registered", but ephone 6 has the field "available_line" set to "0".

On the phone, we can see "SRST Fallback Mode Operating" but no line on the phone.

The Network config on the phone shows "Secondary Callmanager: Active"

It's very strange why no line comes up on this specific phone

I already upgrade the IOS on the 2800, it's not better.

Anyone help ?

Thx

Fabian

It's pretty hard to say something without the config info.

Check/increase "max-dn"?

Don't think it's related to this field since I have only 7 ephone and 9 dn on this site...

But here is the "sh call-manager-fallback":

Phone in Fallback mode... Available line 0 ???

Hi,

I got a similar problem:

CUCM 9.1.1a

Cisco 2821 running c2800nm-ipvoice-mz.151-4.M6.bin

SCCP IP Phones 7941 & 7942

My IP phones are registering on VGW, but don't have a line. I tried many loads for the IP Phones (8.5.4 till 9.3.1) and other IOS 12.4.24T on VGW, but still no phones registering with a DN.

Have you found a solution?

Hi David,

       I got the same issue with you. I wonder if you have resolved it ? how to do it ?

Hi Tom,If you set an old load

Hi Tom,

If you set an old load, then the phones will have the DN. But the old load will not work with +E.164 numbers, so this was not a solution for me. And Cisco doesn't do any development anymore on those old phones, so SRST is not working as it should...

David
