#2

You have three different conversations that are having retransmitted frames (one on the sixth attempt). I would try and fix that first. The obvious reason would be that your network is overloaded.


#3

thanks for reply
i am using the two mobiles connected , your saying that network overload. ??


#4

You are losing a lot of packets. Either the network is overloaded, or you have some systematic misconfiguration that causes all of certain types of packet to get lost. The latter would normally result in the call dropping after about 30 seconds, so I suspect the former.

In any case, you need to find out why you have so many retransmissions.


#5

A second good reason would be that the SIP phones are not working as they should … (network is hardly ever a problem, usually it is a SIP phone issue).
