SIP Enity Link

SIP Enity Link

SIP Enity Link

(OP)


Hi All,
I have an Issue I can't get my Entity link between the session manager and the CM to come up. The SIg group is up and the trunks are in service but the TCP link will not come up.

CM 7.0
SMGR 7.1

RE: SIP Enity Link

CM will mark a sig group up if it gets any SIP response from the far end node name. 404 not found, unauthorized, whatever - that's "up" as far as CM is concerned.

SM's entity link monitoring is telling you when it sends an OPTIONS ping to CM, it gets no response, that that's why it's 408 and timeout and down.

Typically CM won't respond to SIP messages for things it doesn't have a sig group for. Hypothetically, if you typed in CMs IP wrong in the entity in SMGR, then SM could get that timeout and if you programmed your sig group right in CM, CM would get some response to it's options pings from SM (even though SM has no config/wrong config to route calls) and CM would show it happy and have a sig/trunk in service.

When it cm try to register I get the below trace

RE: SIP Enity Link

Verify your node names/IP are correct and verify you have the correct far end node name in the signaling group.

RE: SIP Enity Link

(OP)
The Node name IP are correct

RE: SIP Enity Link

What about the far end node name of the signaling group?

RE: SIP Enity Link

(OP)
The Far end 192.168.16.246 which is the SM ip address
The Near End is 192.168.16.244 Procr IP

RE: SIP Enity Link

One of these is the issue, Node names are incorrect or mis-matched, far end network region or the far end domain name. This is a TCP SIP trunk correct?

RE: SIP Enity Link

(OP)
yes it is TCP

RE: SIP Enity Link

(OP)
If you look at the information you will see the IP address are correct.









RE: SIP Enity Link

Ok, is network region 100 connected to the network region procr is in?

RE: SIP Enity Link

(OP)
See Network region100




RE: SIP Enity Link

Status the signaling group for the trunk and post it please.

RE: SIP Enity Link

(OP)

RE: SIP Enity Link

Also turn off Initial IP to IP Direct Media to no on the signaling group. This will cause issues down the road.

RE: SIP Enity Link

(OP)
I have done that.

RE: SIP Enity Link

(OP)
When I busy the signaling group and return it to service I can see this "481"

RE: SIP Enity Link

DO you have a proxy route pattern selection for this location?

RE: SIP Enity Link

(OP)


RE: SIP Enity Link

Display locations and look at the entry to the right.

RE: SIP Enity Link

RE: SIP Enity Link

Is this your first SIP trunk you have built on your system? Let me know if it is I have a step by step that will help you considering I can't see or touch all the pieces in your switch.

RE: SIP Enity Link

(OP)
yes this is the first SIP trunk

RE: SIP Enity Link

Ahhh. OK that makes a lot more sense. Private message me your info and I'll send you a doc when I get home tonight. One of the things it covers is the proxy route selection. You are really close. Build a route pattern for this SIP trunk and add that route pattern to the location. Now I'm not sure how you plan on using the SIP trunk but if you are connecting to another switch you will need AAR to route the call over the SIP trunk to test. Or for an SBC. Make sure you set up you private/public unknown tables too.

RE: SIP Enity Link

(OP)
Thanks , I will PM you. Well I'm trying to establish the sip trunks between the CM and the Session manager.It is usually straight forward I just don't understand what is going on here.

Thanks for all your help thus far. I really appreciate it.

RE: SIP Enity Link

(OP)
@fondog2- I don't believe I can PM you. I looked all over the site I don't see how I can PM you.

RE: SIP Enity Link

Try this link. Keep in mind this is TLS but keep your ports at 5060 for TCP and you should be good. A lot of good information in this doc.

RE: SIP Enity Link

(OP)
No Link in your post. can you send it again please.
