hi any help out there…any idea…please… 
Hi
Well a log file output with no information as to what type of call what its calling isnt going to get much response
Is this a call to a fax ? or Hylafax ? what codec have you got eneabled ?
To get answers you need to give information.
Ian
ok…im sorry for that…I missed that information.
I’m using Asterisk server- VOIP-SIP-Soft phones and astguiclient dialer s (vicidial)…codec G729.
im having log error like that when times that calls cannot be heard by other party…
hi- anyone can help me with this…please…
If you look in rtp.c you will see that it puts out “Read too short” whenever it’s reading data and the data received is not of the expected length. In other words, either a logic error (maybe due to some aspect of your configuration) or some kind of transmission error (probably due to a hardware problem). To find the reason you are going to need to do some detective work and eliminate possible causes. Ask yourself the following kinds of questions, and give the same kind of information if posting for further help:
-How often does it happen? (all types of call? every call? most calls? less than half? rarely?)
-Has it always been like this? If not, when did it start, and does that coincide with any change you are aware of?
-Does anything make the problem go away?
It may well be a hardware problem… phone line… card… router… cabling…
hi…ive tried isolating this problem…as i observered it happens when my asterisk CLI are flooded by calls…that error appears then simultaneously bad voice quality happens the the client cannot hear the caller…sometime it can be heard but chuppy & echo on voice…
