[Asterisk-Users] Desired Install in MotorHome
I've got a client who would love to be able to leave an asterisk server running sompelace, and achieve telephone connectivity using an IP phone from within his Motorhome in his words I want to be able to work from a mountaintop in Glacier National Park I've done some initial testing, and a SNOM200 SIP phone comes close enough to working that I have not ruled out the idea as completely un-workable. I understand that this is an extreamly hostile environment, the satelite uplink itself introduces too much latency for a standard configuration to work (1500ms) which is most likely where the problems come from. What I'm wondering is if anyone has ever succeded in making a setup like this work. Different protocol (H.323 MCGP etc) or different codecs? Our testing in his driveway revealed the following. 1. Incoming calls achieve a ring almost immediately, when answered there is 1 to 2 seconds delay in the conversation (like a really poor trans-atlantic call) 2. Outgoing calls fail... the phone returns Proxy Authentication Required however a few seconds later when the handset is picked up the inbound leg of the RTP stream is preseant on the phone. Outgoing audio is non-existant 3. Attempts to disconnect from that audio stream fail, the * server is simply not seeing the hangup from the phone. So whats everyones opinion, worth exploring further, or am I wasting my time trying? Thanks in advance. Paul M.

Can you stick an Asterisk box at his end so you can speak IAX over the link? It may not help with the massive delays (which is going to be inherent in any kind of VoIP over the link) but the signalling should be a lot more reliable. -- PGP key ID E85DC776 - finger [EMAIL PROTECTED] for full key ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Oh, now thats an idea... I'll have to dig up a spare PC and try it... he's got 50amps available, why not burn it :) On Wed, 28 Jul 2004 16:12:52 + (UTC), Peter Corlett [EMAIL PROTECTED] wrote: Paul Oster [EMAIL PROTECTED] wrote: I've got a client who [wants VoIP working over a very high-latency link].

Being a former victim of Starband Services, I'd say chuck the connection and find a different way to connect. Your customer will never have a truly reliable connection, and what he has probably won't be usable. 2s voice delays are disturbing and frustrating. Further, an Asterisk system would be overkill anyway, as it wouldn't be able to do VM or IVR or any such app while his mobile home is moving. Alternatives would be SprintPCS's data service which usually clocks in 120kb/s on www.wapspeed.com, or T-Mobile's mobile internet service, once they implement EDGE nationwide. Of course, your customer will still be out of reach in large parts of the country... But while we're talking GSM or PCS services... Why not get a good tri-band phone instead? -Original Message- From: Paul Oster [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 28, 2004 9:30 AM To: [EMAIL PROTECTED] Subject: [Asterisk-Users] Desired Install in MotorHome I've got a client who would love to be able to leave an asterisk server running sompelace, and achieve telephone connectivity using an IP phone from within his Motorhome in his words I want to be able to work from a mountaintop in Glacier National Park I've done some initial testing, and a SNOM200 SIP phone comes close enough to working that I have not ruled out the idea as completely un-workable.

If all you want/need is an IAX connection, wouldn't an IAXy be a better choice from a power and space conservation standpoint? -- Greg Broiles, JD, EA [EMAIL PROTECTED] (Lists only.
