Cisco ATA 186 SIP and Asterisk – HowTo

ATA186 configuration.

The ATA configuration is well described by Cisco you will find pointers on the following page
Asterisk phone cisco ATA18x

For a 5mn quick start do the following :

Connect your ATA on the Ethernet, it will get an IP address via the DHCP. Look in your message log to see which IP address has been allocated
Connect with a web browser on your adaptor http://the-ata-ip-address/dev to get access to the configuration.
Set UID0: to your-login-line1 ; This will be reuse later in asterisk configuration as the end point ID (Channel in sip.conf)
Set PWD0: to the associated password
repeat for UID1 and PWD1 for line 2 ; Note the UID1 MUST be different from UID0

Set UseLoginID: to 0 ; If you want a loginID different of your end point ID set to 1 and fill in LoginID0: and LoginID1:
Set GkOrProxy: to the IP address of your Asterisk server (or SIP proxy/gateway)
Save your configuration.

You can see my ATA186 configuration in the joined file sip.ata186.conf.pdf

/etc/asterisk/sip.conf

[general]
context=[internal] ; Default context for incoming calls
allowguest=yes ; Allow or reject guest calls (default is yes, this can also be set to ‘osp’
bindport=5060 ; UDP Port to bind to (SIP standard port is 5060)
bindaddr=0.0.0.0 ; IP address to bind to (a good idea to restrict that to what you really want)
srvlookup=no ; Enable DNS SRV lookups on outbound calls
pedantic=no ; Enable slow, pedantic checking for Pingtel; This section declares a Cisco ATA with 2 analogue lines attached.

; This section declare the Cisco ATA186 Lines 1 and 2

exten => 112,1,Dial(SIP/ata1-line2,45,o)

;for info integrate a MGCP Cisco ATA 186 (see related conf pdf)
exten => 121,1,Dial(MGCP/aaln/1@000e83e530ae,45,o) ; dial end point aaln/1 in MGCP Channel (see mgcp.conf) 000e83e530ae, rings to to 45s , pass the CallerID as received in the context.
exten => 122,1,Dial(MGCP/aaln/2@000e83e530ae,45,o) ; dial end point aaln/2

You are done.
