Dear Brothers And Sisters Of This Community, Salute
i have bought an amazing Asterisk Based IP PBX (ZYCOO ZX20) its small in size portable and have modern design and i bought 6 of Cisco 7940 Phones with SIP firmware, But the problem is i don’t know how to configure the phones to communicate with the IP PBX because its my first time installing.
Due to my search on the web i know its possible to make them work together but i have no idea how, i am blank in this as of its my first time.
i have made some extensions on the ZYCOO ZX20 but i have no idea how to put the extension number, username and password on the Cisco 7940 Phone
Cisco 7900-series phones are a bear to configure and walking someone through the process is arduous. You’re going to be doing some Googling. Good luck.
I did my goggling and sent messages for people who succeeded but no reply. and i had a document about the process of TFTP config File but my IP-PBX may not have this feature. but there must be a solution i didn’t join a huge community board to get a reply (do some goggling) so plz help.
But I Really Thank You For Passing By And At-least Reading My Problem.
what really makes me surprised that the whole Asterisk Community is watching and no one yet came up with a solution. i guess … or my problem may not worth to waste time on it to reply with a real solution.
I have managed to solve one of the problems, now the phones are registered on the IP PBX as SIP Extensions, and I can make a call to the PSTN line connected the FXO port.
My Plan Diagram
Each extension with Cisco 7940 phones I made a call from the IP PBX Network to the PSTN Line to my mobile Phone and it works perfectly no problems at all.
From The Cisco 7940 Phone I tried Making a call to the other Cisco 7940 Extension, The IP PBX replies that the extension Is Unavailable ?!?!?!
I tried calling the the phone through the PSTN, The IP PBX always replies to the caller “that extension your are trying to reach is not available”.
The Following Conditions Works
Now why is that happening ? does any of you have any idea about whats going on ?
whay cisco phones can make calls to outside world but dont communicat internally with other Cisco extension ? and why it can communicate internally with the CSIP app on the Smart Phones but not the opposite ?!
I don’t believe that any VoIP over Wifi system works perfectly. I would always expect voice quality and latency problems.
You haven’t provided nearly enough information to debug your problems. People who answer here are not going to spend more than one or two minutes on your problem, so need all the relevant configuration and suitably detailed logs, with the problems highlighted, to stand a chance.
The relevant parts of your configuration files and a log of sufficient verbosity (at least 3) that it clearly shows the progress of the call and diagnostics as to why it is failing.
You’ve reached the point where I believe you need more hand holding than is reasonable for a peer support forum. You can request paid support on the Biz and Jobs forum.
