Dear All,


This is my first post on this mailing list, So my hopes are so high.


I am getting MTP receivebuf issue, The problem arises when there are above
25 active channels. I am using chan_ss7 version 2.1, asterisk-, and


Now, at first things work well:

"ss7 link status" shows that both link are INSERVICE.

"ss7 linestat" shows that all CICs go into Idle status.

Calls flow in both directions ok, but after 10 to 15mins. Eventually,
something exhausts itself and everything falls apart with the following
message flooding repeatedly,

mtp.c:413 mtp_put: Full MTP receivebuf, event lost, type=15.


My configs are attached above,


Please help me out its urgent..
