I have an installation utilizing * with an AVM C4 (ISDN card). Using
softphones (SIP and IAX) I have sound problems, like echo.
Question: Does anyone have an FXS card, like the TDM400P, for the
internal extensions, and uses ISDN to dial out?
Any and all information regarding the sound quality compared to a
regular ISDN PBX is greatly appreciated.
If the sound quality is on par with the ISDN PBX a rollout of Asterisk
to more customers would be a feasible idea. Right now, the sound quality
is just not enough for day-2-day use, when using soft phones.
