I'm constantly upgrading to new releases and sound is still very bad. (i can't understand to SIP caller on the ISDN side). I think it is caused by echo because it's different with different analog phones on ISDN side of asterisk. But i did not experience this with same older patches.

To be clear, SIP caller can hear everything clear but ISDN caller can not understand.

What I found different is, that with older patches there was about 1024 interrupts per second in system, but with newer patches, there are only 256 ints/sec. So I think the worse echo is caused by other handling of buffers/interrupts. Is it possible?

Hi there
i have complained for many weeks about problem with chopped audio with all rel
607.
Now i have tested a few calls [EMAIL PROTECTED] 2.8 beta with path 625; i tried with another ISDN and i experienced no unclean audio. Conclusion: issues are with my isdn, driver is ok; or, driver has trouble with certains isdn telecom TA like mine one. This problem was signaled to me by Furio Merlo (thnx to him!) in a private mail. For Daniele: what can i do now to solve the issue? call telecom for bugged NT1+ ??
Or you have some other suggestion?
TIA
        Maurizio
