I have an SV9500. It has 3 PIMs for some analog line cards and PRI cards, and otherwise the terminals are 90% IP terminals. The music on hold is played by an MP3 player and its output is punched down on the EXT/ALM cable.
On internal calls (IP-to-IP or IP-to-TDM) the music plays just fine. However on external calls, be it incoming or outgoing, which are handled by different routes and different telco-s, the music gets distorted. There are sections of the music that are playing OK, and other sections are just a distorted mess. It's alwaus the same sections that are distored.
Those incoming / outgoing routes have been handled by the same teclo and the same PA-PRT cards. I just did one more round of tests and actually noted that the problem occurs only if the external caller/called person is using a cell phone. If the external person is on a landline, the music sounds clean.
So I have:
MUSIC - TDSW - IPPAD card - IP phone - IP phone: sounds great
MUSIC - TDSW - PA PRT Card - Telco - landline: music sounds great
MUSIC - TDSW - PA PRT Card - Telco - mobile used: music is a distorted mess
Anybodo has any ideas?
