Two weeks ago my wife told me that the small snom m3 handsets are not working as well as they should. To be specific, when she’s in the front bedroom the call quality is not good. I was out of town at the time but eventually got around to looking into the matter.
It’s is a simple matter of signal propogation. That bedroom location is the furthest possible point from the base radio, which was in my office.
Jared Valentine has posted an interesting description of a system he developed for automatically manipulating QoS & bandwidth allocation to support the use of VOIP over his DSL service. He calls this “Application Aware Triggered QoS.”
He described his initial problem as being trouble with inbound bandwidth management. This is something that I’ve never experienced myself. My trouble was always related to limited outbound bandwidth.
There’s been an odd converge of concerns around this place. The SIP-GSM gateway is about to arrive so I’ll be tinkering with Astlinux again. Also our doorbell is broken, which makes receiving deliveries a serious drag.
The doorbell is physically located at the gate in the front fence. There’s a zip cord line that runs underground from the house and a simple momentary contact switch in the frame of the wrought iron fence. It seems like there’s a problem with the underground line, not something that is easily repaired or replaced. The rest of the works are located in a central closet, with a second ringer in the office.
The postal carrier left a tag on Friday. The Portech GSM gateway will arrive this week. Sadly, I must to be out of town most of the week. Perhaps I'll be able to get started with it next weekend.
Some reaction to the snom review is starting to trickle in. One reader, Lonnie Abelbeck, noted that he had an issue with daylight savings time on his snom m3. He sent the following message;
Michael,
I read your review of the SNOM m3 in SmallNetBuilder, excellent review. I recently purchased the same m3 setup you have, very pleased as well.
One issue that I think I solved is the daylight savings settings, the defaults did not look correct to me.
For help, I referenced Polycom’s docs using the same platform…

The good folks at www.smallnetbuilder.com have this morning published my review of Snom's m3 SIP-DECT phone.
