HI.

SV9300 sip trunk to carrier

Access code 0(LCR:A126)

User number 2000
Virtual extension 2444

2444 call forward to 0,002NNNNNNNXXXXXZZZZZZZZZZ(Total 25 yards)
N=Other PBX number
X=Walking toll restriction code
Z=Local number

2000 call 2444

CM85 Y=6: 25digits
I can't see SV9300 throwing out the packet
CM85 Y=6: 24digits
I can see SV9300 throwing out the packet

Looks like a system restriction.
Does anyone have a good suggestion?
Thanks.

Looks like you found a bit of a bug, although dial strings wouldn't typically be that long anyway. Is there any way you can create a workaround by making a "shortcut" dial code on the destination PBX that would eliminate the need for some of the digits?

hi toner

Maybe it's really a bug.
I tried it with new SV9300
This problem still exists

Short code dialing , tried to use CM8A9XXX prefix code, speed dial,
Over 24 yards , all failed.

New idea is to use VOIP Gateway.
