Using windows 8 Push notifications on Asterisk and PJSIPS

Using windows 8 Push notifications on Asterisk and PJSIPS and Zoiper soft Phones

I have decided to dedicate some time to make a great system that should soon handle Microsoft Push Notifications, as well as Google and iOS using Asterisk sip with or without PJSIP and/or IAX with good debugging and error reporting. Since I Grabbed my new Nokia Lumia 530 for only 30 bucks, I’m compelled to get it working so everyone can experience the benefits of Microsoft Push Notifications and VoIP Extensions.

I have received most of my Bases from Zoiper (First free Mobile sip phone open to use on any PBX for windows 8 phones)

http://www.zoiper.com/en/tutorials/push-notifications

Also Took some debugging methods from

http://pbxinaflash.com/community/index.php?threads/wp8-zoiper-client-push-notification.15832/

There are still a lot of issues with this, and so far I have gotten SIP to work, still working on PJSIP but got it working with a ugly hack which should be fixed soon.

OPERATING ENVIRONMENT:

Asterisk: version (13) running as full VM on a Microsoft Azure server (Should Work with any version)
FreePBX version (12) (Should Work with any version)
Zoiper, Windows Phone Edition (v.1.0.2.0) as SIP client. Configured for “Push Notification” as per “Help, Tutorial…” section in the settings page of the client itself.
CentOs 6.6 (shouldn’t matter to much though)

BACKGROUND:

“Push Notifications” tutorial published by ZoiPer

IMPLEMENTATION:
The somewhat modified / corrected shell script (see below) from the tutorial is used to send the push notification to Microsoft’s MPNS servers, to notify the phone of the incoming call.
I Followed Manfred Koroschetz in calling it “zoiperpush.sh” and to place it in the “/var/lib/asterisk/agi-bin” folder, giving it permissions (+x) and user:group (asterisk:asterisk) so that asterisk can execute it.

Download The most up2date files:

{phocadownload view=file|id=9|target=s}

{phocadownload view=file|id=10|target=s}

In my concept ill be dedicating 10 extensions for windows phones 0-9 and will work with another 10 for iOS and Android later

Setting Debugging will display as much info about the channel as i could.. but soon will also send email on reason for fail if failed.

Zoiper	Asterisk	PJSIPS	IAX
On my private server it seems everything works but when the script is ran and Microsoft sends a signal to Zoiper for registering , All the extensions on the phone register except the one where asterisk and the phone is behind Nat.. I will be doing further testing though on this	Seems asterisk and Zoiper both behind Nat, the registration after push misses the asterisk behind the Nat	My first problem with PJSIP and Asterisk13 was During Registration it was kicking out the URL and sometimes even rejecting registration.. By default PJSIP has strict Registrations enabled , so i had to disable that before compiling PJSIPS: echo “#define PJSIP_REGISTER_CLIENT_CHECK_CONTACT 0” > /usr/src/pjproject-2.2.1/pjlib/include/pj/config_site.h which allowed me to register, but still removed some headers lol	I hear IAX doesn’t support headers and if so I’m unsure as of now how to catch the URL using IAX.
Sometimes the registration screen is stuck on registering… hitting the connect button does seem to reconnect to asterisk but doesn’t show on the phone in curtain circumstances	I also removed Qualify in my testing, since dial plan seems to fail even if registered but qualify fast talked to phone in allowed time	I have asked Freepbx / Asterisk to see why these push headers are stopping me from registering: http://community.freepbx.org/t/pjsip-headers-are-being-rejected-or-altered/26463 https://issues.asterisk.org/jira/browse/ASTERISK-24654
I do not believe asterisk is accepting the registration limit that Zoiper is trying to establish, I think the Sip Max registration is what is being forced. If unchanged, registration will die soon.		Even after phone registers with push, there is no way to extract the data from PJSIPS in asterisk Dial Plan as of yet, I was told this should change in a couple weeks
It seems even after upgrading to latest version when the windows phone restarts even though it shows codecs enabled they really are not. [2015-01-06 09:13:44] WARNING[59719][C-0000000f]: channel.c:5070 ast_write: Codec mismatch on channel PJSIP/3003-0000001b setting write format to ulaw from none native formats (nothing) [2015-01-06 09:13:44] ERROR[59719][C-0000000f]: channel.c:5336 set_format: Unable to set format because channel PJSIP/3003-0000001b supports no formats – if i unregistered all extensions except the one testing, i don’t get these errors, other extensions has unsupported video codecs, since pjsips wasn’t compiled with video it should error , just not with this extension.
