I have asterisk installed on a Pentium Celeron 366Mhz with a ISDN Modem using Isdn4Linux linking to a number of sip phones, no problem there. Only when i get a phone call coming from the isdn line (BRI) them in the beginning all is quite well, but after a while there come’s a delay from about 2 to 3 seconds (mainly outgoing)
Loads rais to about 0.70 to 0.80, mem is steady.
Does anybody have any idea how this comes? What can I do about it. Would an faster cpu solve this problem?
