CME 10.5 to PBX in a Flash trunk

Hi

I am very new to freepbx, I am currently looking after a PBX in a Flash setup and trying to setup a trunk to a call manager express setup in another office.

Extensions in asterisk are 1XX, extensions in CME are 2XX.

I have looked over several configuration examples but cannot get calls to work properly between the two. Current configuration below:

CME:

dial-peer voice 100 voip
description — CME to FREEPBX —
destination-pattern 1…
session protocol sipv2
session target ipv4:192.168.80.254
session transport udp
voice-class codec 1
dtmf-relay rtp-nte
no vad

dial-peer voice 200 voip
description — FREEPBX INCOMING —
destination-pattern 2…
session protocol sipv2
session target ipv4:192.168.80.254
incoming called-number 2…
voice-class codec 1
dtmf-relay rtp-nte

and on the freepbx side:

SIP Trunk:
Name CME-TRUNK

Outgoing settings
Trunk Name: cme-out
Peer details:

host=192.168.78.250
type=friend
context=from-internal
qualify=yes
dtmfmode=rfc2833
disallow=all
allow=ulaw&alaw
nat=no
insecure=very

Incoming settings

User context: from-internal
user details:

type=friend
context=from-trunk
host=192.168.78.250
dtmfmode=rfc2833
disallow=all
allow=ulaw&alaw
nat=no
canreinvite=no
qualify=yes

I have then created an outbound route and associated the trunk with it.

Any suggestions?

My suggestion use FreePBX!

That’s not currently an option unless you know how to get Cisco 8811 handsets to register with freepbx. They aren’t in the supported handset list.
