Hi All, I am new to Asterisk and VOIP. I managed to get it working with sip(X- Pro) and skinny(Cisco 7940,7960). I have a call manager to which all the phones are connected.

Thanks & Regards, Gurdeep

Hello, Could somebody tell me is it possible to use asterisk without RTP proxying in SIP<->H323 calls? I mean exactly what canreinvite=yes option do in SIP<->SIP calls. I don't need a transcoding, only a signaling conversion, and this is possible with some softswitches, so i wondering what about asterisk. Same question about H323<->H323 calls I'm using NuFone

Hello All, Finally I realised that the Asterisk demo setup didn't include support for h323. (Maybe it should have been obvious) so I went to work out how to get the h323 channel running. I had openh323 and pwlib installed as I'd been playing with vocal so it didn't take long to do cd asterisk/channels/h323; make; make install; make samples, copy the pwlib and h323 libraries to

hello Dmitry thank you for your reply.

Hi all, What is the correct way to give one non-root user the ability to use DTrace with providers running in a process by another user? Through the Web Stack project and some work by Ludovic Champenois and Nasser Nouri, we have done a bit of work to bring together parts of chime, the Web Stack Apache, Ruby and PHP providers, and stuff reused from the DTrace toolkit. It''s in

Hey guys, When a call comes in via the PSTN to our Call Manager 3.2 and is forwarded (via unity and H323), the caller id is set to our Unity Voicemail instead of the caller id from the PSTN. We're using the oh323 channel in this case. Has anyone experienced this issue before? Any solutions? Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, I''ve been Googling this one for a while now, and haven''t found a satisfactory answer.

Aloha, I have a Cisco Gateway the is functioning as my SIP Gateway to the PSTN. I have an Asterisk box, RC2 with a for port FXS card providing dialtone for a Norstar Key System.

Our outsourced IT department has decided to use white listing on the firewalls for outbound ftp. I was given a list of sites our lab had accessed via ftp and eventually tracked them down to Linux machines running yum. They are all CentOS 5 or 6 with a smattering of 7. It is impractical to list all the possibilities since they change on a regular basis. Also any 3rd party repos we need are

hi .. i've just installed and licensed an instance of the G729 codec. I am trying to connect through asterisk to Go2Call server .. According to their info it involves dialling extension 729 on voip01.go2call.com, to get the IVR. my extensions.conf shows : exten => s,2,Dial(OH323/h323:729@216.52.153.206) which I think is correct, I have G729 enabled in the OH323.conf file and it seems to

Hello All, I am trying to setup a SIP to H323 system using SER, Asterisk And GnuGK. Following is the configuration: CISCO ATA (NAT) -> SER -> ASTERISK -> GNUGK My Cisco ATA is registered with SER and When I dial a number, SER forwards the call to Asterisk, and Asterisk forwards the call to the GateKeper. This is ok, call reaches the gatekeeper, however the gatekeeper drops the call

I'm trying to use a Howlink CL-100 ip phone with * It's h323 phone with very limited protocol support. But it's enough that I can use it to dial netmeeting client and artisoft pbx just fine. When I try to dial my * with it using either chan_h323 or oh323, it seems to fail on negotiating H245. Maybe this phone doesn't support it? I've used all different versions of

Hello... I'm having problems with H323/G729 setup. Below is the output of h.323 debug when making a call. I use a SIP phone connected to an * box in the same LAN. The * connects to a h323/g729 PSTN terminator through internet. Calls rings and are answered in the other side, but I get no sound at all nor the other side does (complete silence in both sides). I thought this would just happen
