Has anyone experienced,Music on hold getting distorted when a call through a gateway is put on hold from the CUCM?

Hi,

If I simply explain the network of mine is that we have a CUCM with some IP Phones , and also the CUCM has a SIP trunk configured to a gateway which then connects to a analogue PBX via a DPNSS link. Calls can be made between the CUCM IP phones and the Analogue phones connected to the analogue pbx via the SIP trunk and all looking good. When I put the call on hold from an IP phone, the analogue phone can hear the music on hold fine up to 2 mins 40 seconds, then the music on hold starts to distort.

I am just wondering, if anyone has experienced the above and if so know what is causing the issue? Thank you

Hi gaya,

I never have worked with DPNSS link before but did you check if it s a network issue? What CUCM version are you running? Please give us some additional information about the gateway.
