[asterisk-ss7] chan_ss7 + Astersik JitterBuffer

[Mr.Surender Reddy]

Dear sir,
             Thankx for the Mail.I have built with asterisk with jitter
buffer patch for 1.2.9 for the latest one there was no change it was the
same.But when u said me to compile with chan_ss7 with -DAST_JB added to the
CFLAGS of the chan_ss7 Makefile if you have built Asterisk 1.2.x with the
jitterbuffer patch applied this is not clear for me to Check it sir.As per
my application we have Dell Power Edge with Digium card the server has 8
Gbram and Dual processor with Raid 5 .We are using the SS7 with asterisk for
my calling cards business sir.People are not buying the cards because of the
Audio lost or gichhy problem of audio.we are using Completely Sip platfrom
sir.If u can make the things little easy that would be fine for me sir i
hope u will not mind in making the things clear.

regards
surender
