we are having serius problems with calls not geting in/out our pbx

 

The caller gets an error in his display

 

The callee barely has the chance to hear the phone ring then sees a missed call

 

At almost exactly the time that the call fails I see this message in the logs

 

Call limit reached. Call ports 55, g729 50

 

and if I do a tcpdump I see either one of these two sip errors

 

SIP/2.0 415 Unsupported Media Type

 

SIP/2.0 501 Not Implemented

 

but at the same time in status -> general I see only 25 call legs:

 

Calls: ... 10/25 Calls

 

From what I can tell when ever I hit 20 call legs the errors appear. When I fall bellow 20 the errors stop.

 

All these hapened today after we’ve made an upgrade from ver3 to ver4

 

status -> general has this info:

Hmm at first glance I would say revert back to the previous version.

already reverted but that's not a permanent solution

It could be that the definition of calls and call legs has changed between 3 and 4, I don't really recall any more as this is already a couple of years ago.

I thought of it also so let's see if you can help me grok the info from the system. On settings -> general the system reports:

> Calls: 2251/1599 (CDR: 3371/2421/3925) 13/26 Calls

 

I guess that this means 13 calls with 26 call legs - am I right (I do see around 13 calls in status -> calls)?

 

At almost the same point in time in the logs I see

> Call limit reached. Call ports 55, g729 50

 

I also guess that this means I using 55 call ports for g729 calls while my limit is 50 - am I right?

 

Anything else you suggest I check out in the logs/sip traces?

 

Also is it normal for the system to emit either one of these messages when it thinks the call ports limit has been hit?:

> SIP/2.0 501 Not Implemented

As far as I can remember, in version 3 and also in early version 4, it was "all or nothing" regarding G.729A. This codes is special because it must be licensed per call from the patent owners and they don't change their contracts for us. The argument was that you can re-INVITE a call with G.711 and switch to G.729A; so it would eat up one G.729A license if you use it or not. Later, we introduced some more intelligent way to offer the codec or not. That definitively explains the 415 error messages.

 

The 501 messages are usually for requests that the PBX does not process in that context. For example, if you disconnect a call and the call object is already gone, than the PBX would answer a BYE with 501. This is perfectly okay; in later versions we beautified that a little so that you get a 200 Ok on such late packets as well. But the 501 would not be of my concern at this point.

I would say revert back to the previous version

 

after reverting a group of telephones comming from one IP will not register. I see them sending REGISTER packets to my IP (with tcpdump) but pbxnsip sends back nothing at all. This IP was blacklisted during the period that I was running ver4. I'm puzled -- any ideas?
