[Serusers] Open source GSM/CDMA network
by CM0002＠aol.com 11 Jul '06

11 Jul '06

GSM suppliers working on that already and implementing softswitches in order to increase capacity and lower cost. However GSM is circuit switched - not packet switched (except GPRS) and here is the point cost can't really dropped. The way it will be more probably is that GSM CDMA might be used in the furture in the suburbans and in metropolitan areas we will see a WIMAX/VOIP scenario. This will result in a hybrid network for at least a transitional period. We already experienced it with AMPS/TDMA to GSM transition. CDMA (spread spectrum) is almost dead because high cost and leck of roaming capacity. WCDMA/UMTS (spread spectrum 3G) is very expencive and hard to manage (in Europe the launch was delayed by 2 years because hard and software problems). I recently started with a project (small scale) to setup such WIMAX based networks. The aim is to develop a low cost internet/phone network for rural communities in third world countries. Anybody with routing experience who wants to join me on a professional base is welcome. Regards Christian

[Users] Force RTP proxy when calling NATed UAS
by Leonid Fainshtein 11 Jul '06

11 Jul '06

Hi, I would like to force RTP proxy for calls when UAC is located on the public Internet and the UAS is located behind a NAT system. The nat_uac_test() doesn't help in such situation because the INVITE is issued by endpoint located on the public Internet. In other words, I'm looking for a way to get info about the UAS. If it is located behind NAT than I would force RTP proxy. Thank you in advance, Leonid Fainshtein

Hello, We 'd like to prefix something depend on some kind of group membership of users. During radius authorization radius set an avp e.g SIP-AVP prefix:123 I 'd like to set Request-URI according to this avp, but prefix("$avp(prefix)") don't work the uri will be sip:$avp(prefix)12233@... :) as i read pseudo variables is only enabled in xlog and some avpops functions. How can i solve this problem, Another question about acc module loadmodule "acc.so" modparam("acc", "radius_flag", 3) modparam("acc", "radius_missed_flag", 4) route{ #... setflag(3); setflag(4) #... } don't send accounting messages to radius, i must use acc_rad_request? Thanks any help, Tamas
