Often i can see that cic, which is shown on MGC in IDLE state(mml command rtrv-tc), on gateway(as5400) is still in busy state. show mgcp connection shows me the following:

5. S3/DS1-0/29 C=4A05B,2150032,2150033 I=0x17B8 P=16650,0 M=4 S=4,4 CO=6 E=0,0,0,0 R=0,0

and show call act v b shows only one call leg

3FC0 : 1201552451hs.1 +0 pid:1 Originate active

dur 00:18:47 tx:0/0 rx:37568/1127040

Tele 3/0:0 (2150032): tx:1127050/0/0ms g729r8 noise:-120 acom:127 i/0:-48/-87 dBm

only after beginning of auditing process on mgc (sta-aud mml command) hunged mgcp connection usually is dropped. but sometimes on MGCP -> DLCX gateway responds with MGCP -> 1553037 Endpt in transient state

and cic can be freed only after reloading the gateway

It's very possible you are hitting a BUG.

Check the latest IOS available for operation with PGW and try to upgrade the AS.

Hi Dragos

I also think that it's a bug and not a feature :)

Can you tell me which IOS are you using with PGW, because in release notes for MGC 9.4(1) http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/relnote/rn941.htm

i didn't find any usefull information about recommended IOS-es fow mgw
