Mr. Mahmoud, you really rock. you are very good. Keep it up. Please, trust me we will really love it if you could make a video to show us how to configure Asterisk to be able to make calls to PSTN lines (i.e. subscribing to a VOIP provider etc). But maaan, you rock!!!!!
Mahmoud Ramadan Ali Amazinbg tutorials. Thank you so much. I finally got my head around Asterisk. Good Bless you. I am wondering if you could make a video about how to setup Asterisk with a voip services and how to hook that up with an ata device type of setup? many blessings.
I added a new category to my blog "CISCO & Asterisk Integration" to discuss how to integrate Asterisk with CISCO VOIP including CUCM and CME which i already did so the rest of my upcoming posts will be around Phones and ATA integration...
I have finished my book...the guide also has all the materials u need to do the job including the firmware and the configuration files...i hope this will help you :D My recent post Cisco & Asterisk Integration Guide.
Hi Mohammed, Thanks a lot for your youtube videos for asterisk it was helpful. I got a question if you help me that would be great, I have tried G729,G723, G722 and u-law GSM. But still the voice quality is very bad and there is background noise. IS there any codecs which doesn't have any noise. doesn't matter with the bandwidth. you can reply me back on tncybercrime8@gmail.com
I recommend you to use any of the wideband codecs such as G711 or G722 if applicable if you want to use a clear audio channel over the WAN also increasing the jitter buffer on asterisk can improve your QOS but will add some unnoticeable delay...if you still facing QOS issues you must configure QOS on your intermediate devices such as your firewalls...
Hi Brian, You can easily pickup a call by configuring a telephony feature known as Pickup group.This will give you the ability to pickup an incoming call and answer it on another phone. And regarding to your question about queues i recommend you to read about queue configuration including agents and agent groups and skills because you can virtually configure any call routing logic with queue call distribution algorithms.
Thanks! I am currently testing some queing on SIP but have a problem. Once the call is placed on queue, there is no way for any SIP (extension) or agents to pick up that call. Or maybe I can't figure it out, tried to look for solve this for hours but couldn't. Do I have to press something?
The only turn around I did was to add retry: every 5 seconds. But in real life, I am not sure if the phone will ring loud every 5 seconds.
