Digium phone stuck on Contacting sip:proxy@IP:5060

Any normal/softphone works perfectly, but Sangoma (Digium) phones uses an SSL certificate to encrypt phone configuration messages. That certificate expired on May 28th, 2021. The certificate is embedded in the DPMA blob, so it can't be renewed.

Basically  this is the cost of putting binary blobs on your server :(

The solution is to download a new binary blob from digium and to replace the existing one in /usr/lib/asterisk/modules

check https://my.digium.com/en/docs/DPMA/dpma-download for the right DPMA module.

# cd /root
# wget http://downloads.digium.com/pub/telephony/res_digium_phone/asterisk-13.0/x86-32/
res_digium_phone-13.0_current-x86_32.tar.gz
# tar res_digium_phone-13.0_current-x86_32.tar.gz        

# cp /root/res_digium_phone-13.0_current-x86_32/res_digium_phone.so /usr/lib/asterisk/modules

 # asterisk -rx "module reload res_digium_phone.so"

 

 

Asterisk PAGE say time every hour

Digium D6x phones and CyberData SIP Speakers  are used to page.
The phones are also used as intercoms (bidirectional page).

To start, we need accounts for the phones/speakers added to sip.conf:



[phone1] ; Phone
type=friend
host=dynamic
context=my-context
secret=5678
mailbox=319

[speaker1]; Speaker
type=friend 
host=dynamic
context=my-context
secret=1234
mailbox=329
record_out=Adhoc
record_in=Adhoc
qualify=no

Then in extensions.conf, in the [my-context] context, add:

; Paging extensions

exten => 3319,1,GotoIf($[ ${CALLERID(number)} = 319 ]?skipself)

exten => 3319,1,SIPAddHeader(Alert-Info: info=<intercom>) ; Digium D6x require this to enable paging - search documentation for different phone models!

exten => 3319,n,Dial(SIP/phone1) ; this is the phone1 defined in sip.conf

exten => 3319,n(skipself),Noop(Not paging originator)

exten => 3329,1,GotoIf($[ ${CALLERID(number)} = 329 ]?skipself)

exten => 3329,n,Dial(SIP/speaker1,50) ; this is the speaker1 defined in sip.conf

exten => 3329,n(skipself),Noop(Not paging originator)

exten => 398,1,Page(LOCAL/3319@my-context&LOCAL/3329@my-context,di,120) ; Bidirectional PAGE - that's what the "d" does.

exten => 398,n,Hangup()

With this, we can dial 398 and the PAGE should work.

Now, in order to say the time automatically, we need a .call file, let's create /var/lib/asterisk/third-party/say-time.call

Channel: LOCAL/398@my-context

MaxRetries: 10

RetryTime: 5

WaitTime: 20

Context: page-say-time

Extension: 3310

Of course, we need to create the [page-say-time] context in extensions.conf:

[page-say-time]

exten => 3310,1,Answer()

exten => 3310,n,Wait(1)

exten => 3310,n,Playback(at-tone-time-exactly) ; this sound file is already in asterisk sounds

exten => 3310,n,Wait(1)

exten => 3310,n,SayUnixTime(,EST,IMp)

exten => 3310,n,Wait(1)

exten => 3310,n,Playback(beep) ; this sound file is already in asterisk sounds

exten => 3310,n,Wait(2)

exten => 3310,n,Hangup()

and the last step, create a crontab that copies the say-time.call to the astersk outgoing at every fix hour:

0  * *  *  * /bin/cp /var/lib/asterisk/third-party/say-time.call /var/spool/asterisk/outgoing/

Phone extension that rings multiple external numbers (CCME Asterisk)

Skip to end of metadata

o to start of metadata

In this example we want to ring all the external numbers of a few people only by dialing extension 3331.

1: Connect to CCME and create a new dial-peer:

dial-peer voice 3331 voip
 description External Emergency Responders
 destination-pattern 3331$
 session protocol sipv2
 session target ipv4:192.168.0.XXX #(the Asterisk box)
 dtmf-relay rtp-nte cisco-rtp
 codec g711ulaw
 no vad

2: Connect to the asterisk server and add the extension in the default [incoming_context] in /etc/asterisk/extensions.conf: (192.168.0.YYY is the outgoing trunk)

exten => 3331,1,Dial(SIP/5145555555@192.168.0.YYY&SIP/51455555519@192.168.0.YYY&SIP/5145555552@192.168.0.YYY&SIP/5145555553@192.168.0.YYY&SIP/5145555554@192.168.0.YYY&SIP/5145555555@192.168.0.YYY)
exten => 3331,n,Hangup

3: Reload asterisk config and test the extension 

Cyclic paging script

Let's say that we have an emergency voicemail box where our clients can leave us messages if they have a contract for extended hours or a limited response time contract. Let's also suppose that we have a shitty mobile phone provider, whose signal does no goes higher that 3000ft and is not available too far in wilderness, but we still have those old pagers, able to receive the signal even on top of mount Everest. And let's say that we have a bunch of unfortunate enough bastards on call that are supposed to respond to those calls. Now, every week it's some other poor bastard turn to be on call, but just in case he's not available, we might be force to page the other unfortunates, even when it is not their week of duty. And we page them in order, one after another, until one of them login the web interface of our asterisk server or call the emergency mailbox and acknowledge the message.
This is the script that have to be run from cron every */10 minutes on the asterisk server:
