[Asterisk-Users] maximum retries exceeded

[robert ivanc]

Hi,

i've just got 2 grandstream phones and when I try to connect them with * 
I get the following:

 -- Playing 'demo-abouttotry' (language 'en')
WARNING[5126]: File chan_sip.c, Line 464 (retrans_pkt): Maximum retries 
exceeded on call 02da8d3d-a8de-c7e1-5f07-c032ab23d909 at 10.1.1.179 for 
seqno 59134 (Response)

I've seen there was some discussion on this already but i couldn't find 
any resolution. Can anyone help?

Regards,
          Robert Ivanc
