I am using a 4 FXO A400P card on a testing server:
PentiuIm IV 2.8 Ghz
2 Go RAM
160 Go S-ATA Hardrive
OS: Debian Lenny
Asterisk in 1.4
and zaptel is the last version.
When dialing from sip to the pstn i get one or two ring and then blank sound then it's take something like 10 secs before getting dialing tone on the pstn
line adding the r option in my exten to simulate the dialing tone doesn't work ever.
i still have the " 10 sec blank moment"
Does anyone got this problem? Is it CPU problem or something like that ?
I tried a trixbox 2.6 to be sure it's was not my os or zaptel which had a problem but it's the same delay on the trixbox.
You mentioned that the asterisk version is 1.4, but could you tell me the exact version of it? And what are your configuration file zapata.conf. extensions.conf .Actually, there are some people already experienced the delay issue in trixbox . I don't think this to do with the hardware.If you don't have other particular features to test I suggest you try this combination of software(zaptel-1.4.11 and aterisk-1.4.20) instead of the version you owned now. There is solution about solving the delay in trixbox, but I am not sure it whether matched your case.
Any question, please post here!
Let's remove the default version from apt and and install version 1.4.20 of Asterisk and zaptel 1.4.11 from sources.
I will activite debug mode and tell you if we have something new !
Thanks for you help!
