A Physical Power-cycle seemed to fix the issue! I originally reloaded via CLI but it did not take. This seems to have done the work.   Thank you for all your help! Greatly appreciated, I have rated as helpful.   Nic. ... View more

Hi Maren,    The first time I reloaded via CLI it did not have any affect. However I have just done a physical power cycle at the router switch, and this has cleared the issue.   Thank you!   Nic. ... View more

The only way I have tested is via two internal SCCP phones, as there is not yet a SIP trunk service delivered for outbound calling. I have had telephony-service shut for 5 minutes now, I can still call between phones. Neither one of the two I am testing with has unregistered or reset. They act like nothing has happened. I shall reconfigure telephony, but given the above results, I'm not too hopeful.   Nic. ... View more

Shut/No Shut produced no results. When I did shutdown telephony-service, phones still continued to be up and running and could still call between one-another, I assumed this command would halt all telephony activity, am I correct or is something wrong there? I have not deleted telephony-service and started again, as I am sure it would have little impact, but I may do that tomorrow and see what happens. Any other possible ideas? This is extremely unusual behaviour. Still TOH and no MOH.   Nic. ... View more

Nipun,   followed those commands,   redid commands with music on hold from the CME 12 fileset. Same result. No-go.   Skinny Music-on-Hold Process is NOT YET STARTED! ------------------------------------- Skinny Music On Hold Status - group 0 Active MOH clients 0 (max 210), Media Clients 0, B-ACD Clients 0 File flash0:MOH/music-on-hold.au (not cached) type INVALID Media_Payload_G711Ulaw64k 160 bytes G.729 Music-on-Hold File Status No MOH file loaded   Incorrect naming structure from the MOH folder on flash? Tried multiple ways. Otherwise, something else wrong. I used the no form of the moh command, redid it, no created cnf and recreated cnf under telephony service. flashed new moh file to tftp. Nothing.   You mentioned an ip route being needed due to the phones being on a different SVI. Can't see anything wrong but its early hours here so I may be missing the obvious.   Nic.  ... View more

Hi Nipun,   Phones are SCCP. Please see below outputs:   Skinny Music On Hold Status - group 0 Active MOH clients 0 (max 210), Media Clients 0, B-ACD Clients 0 File MOH01.au (not cached) type INVALID Media_Payload_G711Ulaw64k 160 bytes Moh multicast 239.0.0.1 port 2000 route 192.100.20.1 192.100.21.1 G.729 Music-on-Hold File Status No MOH file loaded   Statistic Count ------------------------- ----------- Send queue enqueue error 0 Socket send error 5 Msgs discarded upon error 4   As for the file, it has been a very long time since used, but it was pulled from a working router, have opened it and rechecked. It meets all the listed requirements    Looks like it could be a routing issue as mentioned.   Nic. ... View more

Hi Sam,   Thanks for the reply! Enabled proxy-arp on both voice interfaces, still getting tone on hold, MOH is still not operational.   Nic. ... View more

Thanks Brandon, So I would need a seperate voice port for every seperate simultaneous call into the system and pre-guess the call volume levels? I'm assuming if all licensed ports are busy when someone calls they would just get the automated "sorry, voicemail is busy, try again later" message followed by an automatic disconnect? ... View more
