[Asterisk-Users] Asterisk for voicemail -> C2611XM, 7940 & 7960 phones
Hello, My group at work has a test voip deployment, using a Cisco 2611XM with FXO and FXS modules, and a small number of Cisco 7940 and 7960 ip phones. This is working today, with outgoing calls going over a pair of POTS lines on the 2611XM. I would like to add an asterisk server to the mix, just to add voicemail (at least for starters). The phones, router, and asterisk server are all on seperate private internal networks. I'm very new to all things voice, and have been digging in to the various asterisk docs as fast as I can absorb them. I could use push in the right direction, and some sample configs would be even better. Thanks, --Stafford

[Asterisk-Users] Problems with a combination of AVM B1 and HFC-S on Kernel 2.6.x
Hello List! Several users of a german VoIP-Forum experience the following similar problems when using CAPI with an active ISDN-Card AVM B1 PCI connected to the PSTN and a HFC-S in NT-Mode used as an "internal" S0-Bus to connect ISDN-Phones. The problem is, that when making a phone call from an ISDN-Phone connected to the HFC-S-Card that is meant to be routed to the PSTN through the AVM B1, the voice quality is very bad. It sounds as if someone has a really bad, bad cold. What makes us wander is, that if a call is made from a SIP-client through the AVM B1 to the PSTN, everything ist fine. Calls between SIP-clients and ISDN-Phhones connected to the HFC-CArd are also ok. In addition one user found that if one monitors/records a phonecall made from an ISDN-Phone to the PSTN through the AVM B1, the recorded sound is also fine, only the "live" sound is that bad and we have no more ideas what to try to figure out where the problem is. What we heard, but we still have to verify this is, that on a Linx with Kernel 2.4 everything seems to work. But this is still unverified. The Kernel is 2.6.8 in my case the actual updated Kernel of a SuSE 9.2 Distribution. We were also testing different Motherboards and made sure that there are no IRQ-Conflicts between HFC and AVM card, etc. The Test-Systems had no load and are running smoothly. Any ideas? Thanks, Jui
