I've testing a VG248 operating in fallback mode but can't seem to transfer a call from the analog devices attached. Each time I press the 'Recall' button to initiate it I get a re-order tone.
The analog phones can call other devices fine and recieve incoming calls from similarly SRST registered end points.
IP Phones in SRST at the same time can transfer calls fine involving the analog devices.
Dual-line is configured but seems to have no effect on the VGC registered phones.
Is this a supported feature (I've trawled Cisco documentation) and all seems to imply it should work as configured.
Am I missing a trick?
Sample SRST Config:
max-conferences 8 gain -6
timeouts interdigit 5
ip source-address 172.16.50.13 port 2000
max-dn 144 dual-line
after-hours block pattern 1 900 7-24
system message primary Backup SRST Active
call-forward pattern .T
'show ephone reg' for a VGC device gives me:
ephone-1 Mac:0943.E280.A801 TCP socket: activeLine:0 REGISTERED in SCCP ver 0 and Server in ver 0
mediaActive:0 offhook:0 ringing:0 reset:0 reset_sent:0 paging 0 debug:0 caps:4
IP:172.16.50.58 16920 VGC Voice Port keepalive 166 max_line 1
button 1: dn 1 number 6019 CM Fallback CH1 IDLE CH2 IDLE
So I can see a single line ref.'d here but cannot see a way of increasing the number.
VG248 is operating on v1.3(1) and SRST GW IOS is on 12.4(15)T9 Adv.Ent.
