10 second delay on analog phone on VG224

Good morning all!

I have two analog phones connected to a VG224 which then connects to a CME (v8.1) system.

The phones are working, but when I pick up the handset and dial an internal or external number, there is approximately 10 seconds of "dead air" time before I hear the other phone ringing through the connection.  Also, when I have an IP phone call either of those analog phones, as I lift the handset I hear the tones from the dialed keys and then I'm connected to the caller.

I'm pretty sure this is related to the dial-peer config, but not sure exactly what I need to adjust to fix this.

Here's the appropriate config snippets from the CME:

dial-peer voice 1517 voip

description LL Lobby Phone

destination-pattern 1517

modem passthrough nse codec g711ulaw

session target ipv4:10.62.88.9   (VG224 IP Address)

voice-class h323 1

codec g711ulaw

fax rate disable

fax protocol none

no vad

!

dial-peer voice 1518 voip

description 1st Floor Lobby Phone

destination-pattern 1518

fax protocol none

no vad  

!

voice-gateway system  1

type VG224

mac-address E8B7.487A.4200

voice-port 0-23

And from the VG224:

dial-peer voice 1000 voip

description outgoing calls TO CME

destination-pattern .T

dial-peer voice 1001 voip

description incoming calls From CME

codec g711ulaw

fax protocol none

dial-peer voice 111 pots

description LL Lobby Phone

forward-digits all

!

dial-peer voice 112 pots

description 1st Floor Lobby Phone

destination-pattern 1518

!        

Any help will be greatly appreciated.

Thanks!

10 second delay on analog phone on VG224

It's because dial-peer 1000 on the VG224 is waiting for more digits. You need to be more specific to rule it out for four-digit extensions. For example, a destination pattern of 9.T would at least limit it's use to off-net calls. In that case off-net calls fro mthe FXS port would still wait for the inter-digit timeout though.

Depending on your country you probably do not want to use variable-length patterns. Be specific 9[2-9]...... 91[2-9]..[2-9]...... and 9011T are more appropriate if in North America.

Thanks Jonathan, about 20 minutes after I posted I figured it out.  I added a dial-peer with the [2-9]... variable and it works fine.

Now to figure out COR stuff to keep them from dialing anything but internal extensions and 911.
