Asterisk and Verso’s Clarent Class 5 Call Manager

This is an experience connecting Asterisk to Verso’s new SIP stack in their Clarent Class 5 Call Manager.

Some example providers using Clarent Verso – www.vox.co.za

sip.conf

;registering with the switch
register => phonenumber:password:username@host

;the switch were dealing with here makes use of the auth user option in the register statement
[verso-in]
; incoming calls only.

type=user
context=verso

[verso-out]
type=peer

;outbound calls only
secret=password
username=username

;auth user
fromuser=phonenumber
;From user has to match the SIP device name on the switch or it will be ignored!

insecure=very
host=host
fromdomain=host

;From domain has to match the SIP device domain on the switch or it will be ignored!
canreinvite=no

rtp.conf
;need to change rtp ports

rtpstart=30000
rtpend=65535

;the particular switch I was dealing with had the rtp ports set as stated. it may differ between providers

Then deal with the calls as you would any other SIP provider. Some bugs are still being found here and there, so the wiki will be updated as the bugs are found and sorted out.
