[Fwd: Re: Large issue - having trouble diagnosing.]
thankyou both very much for your swift responses and helpful insight... While my knowledge of administrating Asterisk is fairly decent, i must say my knowledgebase and ability in troubleshooting it is fairly lousy... all these wonderful suggestions you have had about turning this log on here, etc sounds great, but i don't know where to begin on that! how do you recommend i turn these on or

Which SIP phones to buy?
I need to buy some new phones for our own offices. I've used only Polycom phones until now, but I'd like to broaden my experience. I'm trying to decide which phones to experiment with. I have these options: - A combination of Polycom, Aastra and Snom - Just Polycom One the one hand, I'd like to keep things uniform, since it greatly simplifies provisioning. On the other hand, I

PoE switch recommendations?
Hey, all. We're rolling out VoIP, and I'm wondering about PoE recommendations, as we're going to have to replace our current network equipment. My first inclination would be to just plunk down the cash and do a Cisco system, but I'm relatively certain that would get shot down by finance. Any recommendations for a couple-hundred-port solution with VLANs, PoE, and QoS? Don't

packages for ecologists
Hello R-user, sorry for this very off-topic question. But I shall present R to my dept. (pro's and con's and what it can do). The pro's and con's are easy but not what R can do (additional to the "normal" statistics). I looked through the packages, but the enormous amount of packages makes it very difficult for me to decide which one is worth mentioning. I used

Siemens Gigaset IP in USA (S685 IP in particular)
For some unfathomable reason, Siemens USA doesn't offer the Gigaset IP range in the U.S. I'm particularly interested in the Gigaset S685 IP. Since it's DECT 6.0, and there's an English (UK) version, I'm thinking it should work just fine, after dealing with the walwart issue (and maybe caller ID signalling). Anyone imported one from the UK and using it in the US? for how

Transfer caller direct to voicemail
Hi, Our operator frequently gets requests to transfer a call directly to voicemail in order for the caller to leave a message without disturbing the callee. Basicly, I'm looking for a blindxfer to vm. My first thought was to prepend a digit (eg 7) to the extension but this does not fit well with our dialplan. According to an article on voip-info.org Asterisk@Home appears to implement

Multi-line phones - Asterisk uses wrong callerid
I have some phones (and an ATA) that are shared between two users who each have separate voicemail but they are not behaving as desired nor expected. Incoming calls show up on the correct lines. Calls originating from the device are seen, at the terminating device, as coming from the account listed last in sip.conf, regardless of the line selected. This creates three main issues I would like

Vlan question
There is a way to ensure traffic prioritisation...but it can work out a little expensive. 1. Use 3Com 4400 PWR as your switch. 2. Use 3Com NJ200/NJ220 (US) or NJ205/NJ225 (EU) POE Multiport switches 3. Use 3CNJVOIP-CPOD POE --> 7960 POE/Data splitters for power and data connections to the phone. The 4400 Delivers Power to the NJ2xx switches, these switches have 4 ports which can be

Problem with Aastra 480ci and qualify=yes
Hi, We have a few Aastra 480ci phones and we've noticed that in order to get the phone to receive a call, qualify must be = no. Apparently the Aastras do not respond to the qualify message (or respond in a way Asterisk doesn't understand) and Asterisk thinks the phone is unreachable. However, this now prevents MWI from working properly on the phones. Does anyone know how to get MWI

Polycom getting DCHP address from wrong VLAN
Hello, I have been tearing my hair out on this issue for 2 days, any help would be appreciated. We have a normal network and a Cisco SGE2010P switch - a 48 port PoE switch There are two VLANs, 1(data) & 50(VoIP). When Polycoms are connected to the switch with VLAN 50 hard coded in the config they grab a DHCP address from VLAN 1, the PVID for the switch port. The ports have membership in

How to hookup to cell phone for outbound calls?
Hi I need a small PBX for use on the move. This means that outbound calls will need to be made over the cell phone network. Assuming a small hardware PBX with a spare mini-PCI slot or a USB slot then what hardware options do I have to get an outbound cellular channel? Options need to be rock solid, so no bluetooth to a cell phone kind of solutions need apply. Can any of the 3G usb

Sample configs, with the only addition being by SIP phone, and my incoming voip. Last week I got everything setup, calls were working, etc.,. I cam across a tutorial for voicemail, followed it, and it worked. When I call my phone and dont answer, it goes

fsck and guest images
Hey! I have some RHEL6 hypervisors and the VMs are in raw qemu image files in a local raid array linux raid + lvm + ext3. When a kernel update is installed a reboot is necessary, usually it has been more than 180 days since the last reboot and the file system is fsck'd and this takes 2-3 hours. I am curious to know if there is any documentation that addresses the pro's and con's of
