MGCP Caller ID FXO 8.6

[joshhaleaos]

Has anyone got this to work in an 8.6 environment?  It seems to work sometimes and then it stops.  The only way I can get it to start working again is by rebooting the router.  The client is running 8.6 with the 2900 series routers (latest IOS 15.2.T1).  I've got the Enable Caller-ID checked in the FXO ports, caller-id enabled on the voice ports and the MGCP res package installed.

CUCM - 8.6.1a

2901 - 15.2.T1

Hi,

Can you try putting in the following command?

(config)#mgcp persistent offhook

Any success with this problem. I have the same issue.

Hello!

Can you please try under the voice-ports the following command:

voice-port x/x/x

timing guard-out 1000

Then do a shut - no shut on the voice ports

Please make some test calls and let us know.

Jorge

It is true. However, line:

timing guard-out 1000

disappears after a while and the caller ID issue appears again.

Is there anyway to resolve it permanently?

Hi Christapor,

please try these commands in addition to timing guard-out and mgcp persistent offhook

caller-id enable

caller-id alerting line-reversal

caller-id alerting dsp-pre-allocate

Hi Aman,

could this be an issue with the IOS? may be 15.4 ?

I too faced this issue but then i moved to H323, can you help?

thanks.

[Aman Soi]

Hi,

aman

[pgupta601]

i did had to upgrade the IOS to 15.4.

[Aman Soi]

You mean to say caller-ID problem got resolved by upgrading the IOS to 15.4.

Lastly , CallerID is working OK with H.323 and MGCP on 15.4.Please confirm.

regds,

aman

[pgupta601]

Caller id issue got resolved moving to H323....

i was asking you could IOS issue be the cause for MGCP?

i have upgraded the IOS to 15.4  but have not tested MGCP but H323 works fine.

Thanks.

[Aman Soi]

regds,

aman

[pgupta601]

we were on 15.1 first version  dont remember though.

if you have a test environment can you check with MGCP?

thanks.

Why not taking the easy way and insist on an inferior solution ?

With H.323 or SIP, you would have everything working perfectly by now, and many more features and manageability.

Paolo, I like your thinking, I myself have been staying away from MGCP for few years, and only do it when I am forced. I get the benefit from centralized dial plan management, but as you point out too many culprits to deal with.
