[Serusers] CPL

Thu Feb 26 13:14:29 CET 2004

Hi Bogdan,

The version of ser is 0.8.13. (I will update from cvs today)
About the timeout issue, ok, the proxy no answer works with the "tm"
modparams.
My question now is, how to configure a proxy no answer and busy for the same
user who will upload the script?

Thanks again,
Toni

Hi Tony,

First one question: what ser version are you using?

The noanswer issue was previous disscused on the mailing list - here is 
some copy past :

Try to do the followings:
modparam("tm","noisy_ctimer",1) # this will force timeout
modparam("tm","fr_inv_timer",30) # sets the timeout for INVITE to 40 sec
(default is 120)

Please tell me if this works for you.

make sens to do so. If somebody calls user client1, it's script will do 
proxy to himself (to clinet1) and the request will hit again the proxy, 
the CPL script will be run again, and so one.....
