Incoming call fails on SRST mode

Scelo
Level 1
Level 1

Hi there,

Need some eyes troubleshooting an issue here - all incoming calls fails while on SRST, it a new implementation. Can you browse through through my configs and advice as to where am i going wrong:

- Tested the translation rule with success

- Initial had the rule attached on the voice port - no luck, moved it to dial-peer 20 still no luck

- Added .... on my rule - still no luck:

voice translation-rule 1

rule 1 /^7...$/ /011874..../

NB: We use 10 digits internal and telco sends 4.

have you tested your translation rule?

try entering the following;

test voice translation-rule 1 7333

does the output match the DN you are trying to call?

Please rate if helpful

Sorry, hit correct answer by mistake.

I did test the translation rule and yes - it matches the correct DN.

Hi,

Can you try changing the SRST voice profile

!

voice translation-profile SRST_call_Handling

no translate calling 1

!

!

voice translation-profile SRST_call_Handling

translate called 1

!

The 7xxx is a CALLED number

Thanks Alex,

I have updated that and will be testing if it works - will keep u posted. Should it not work - what else could be the cause?

Hi,

Thanks for the update.

If this fix does not work.

Can you please post the "debug isdn q931" of a failed call

Good luck with the testing.

The testing didn't go well - unfortunately i couldn't get traces as i was doing this remotely (lost connectivity to the GW).

While waiting for another day for testing, what could lead to SRST fails with a engage tone? Is there a document with possible symptomes?

Hi

Typically it's a problem with your translations. The best way to test remotely is to (carefully) apply an access list that blocks all traffic from the voice VLAN at the remote site and from the router's IPs to the CUCM servers. That way it goes into SRST, you don't interrupt the data traffic, and you can test and properly remotely debug the calls as you test them.

Regards

Aaron

Aaron Please remember to rate helpful posts to identify useful responses, and mark 'Answered' if appropriate!

Still, it fails. it give a continous tone then engagement tone.

Hi,

Can you add a DP to match incoming calls

Something like this

!

dial-peer voice 1 pots

description *** FOR INCOMING CALL MATCHING ***

incoming called-number .

direct-inward-dial

port 0/0/0:15

!
