UDP Miss A Hangup On SIP

Report
Question

Is it possible to miss a UDP SIP packet to hangup a call? Using 1.4.43 I had a call from on Asterisk box (server) to a low end client (chan_alsa) not hangup.

Could this be due to missed UDP SIP packet to hangup?

Is there anyway for a client asterisk (chan_alsa again) to monitor the connection and if the channel is not there to hangup?

Thanks,

Jerry

Send Fax From Asterisk

Report
Question

Thanks for sharing the link. Actually I'm looking for a different approach without installing/using third party i.e. a user sends an email to Asterisk (which is also running mail service), as Asterisk receives the mail where the mail contains attachment and subject contains destination number, Asterisk will download the file and capture the number and later send fax to destination number just like '.call' file.

Does anyone worked on this scenario? If yes/no, please let me know at earliest.



please check it. might be it will help

It doesn't seem to have any effect on the voice quality but the messages on the console are quite annoying.

PS: The peer doesn't support ulaw.

PPS: Asterisk…
