I've seen this. The SRST feature set in the mainline versions of code
runs behind and is probably not compatible with the version of UCM
you're running. Send us a "show call-manager-fallback" and we can
confirm that, especially considering these are 7962s.

That being said, moving to the latest T train code would be the remedy
for that.

Thanks,

Hi Guys, 

I have a problem with SRST. Phone registers successfully, but it doesn't
show the line number at all. 

Here is a config of SRST Gateway:

call-manager-fallback
 secondary-dialtone 0
 max-conferences 8 gain -6
 transfer-system full-consult
 ip source-address 192.168.1.1 port 2000
 max-ephones 96
 max-dn 288
 dialplan-pattern 1 15.. extension-length 4 extension-pattern 15..
 transfer-pattern ....
 time-zone 53

Phone shows as registered:

ephone-1 Mac:0022.9005.270A TCP socket:[1] activeLine:0 REGISTERED in
SCCP ver 19 and Server in ver 5
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0
IP:172.22.145.15 51524 Unknown 404  keepalive 11 max_line 0

Version of gateway:

c2800nm-spservicesk9-mz.124-25b.bin

Version of CUCM: 7.1.3bSU2

Version of phone firmware: 9.0.2SR2
Phone model: 7962G

What's missing in SRST Gateway? It works fine as H.323 gw.
