I have configured a CME to be the main call processor for 75 new cisco IP phones. Everything is working as expected but I've been asked to connect 2 analog lines that come from an old Harris PBX.
Currently, I can successfully communicate to anyone on the Harris PBX, I just dial the prefix (in this case 8) and then, the 4 digits of the extension (for example 8 + 5002 will connect me to the currently technical support extension on the Harris side). These 2 analog lines should also allow us to go to the PSTN but I'm facing the following issue.
On the Harris PBX, I must dial the prefix * in order to be able to go to the PSTN (from a Harris phone I dial * + 8 digit number), so, if I dial from a Cisco IP Phone the following: 8 + * + the 8 digit number... I always get a busy tone. I was trying to create a new dial peer so the CME would ask for the * but unfortunately, it does not seem to work because I can't call to anything on the PSTN (from the Cisco phone I dial 8 + * + 8 digit number... and I get a fast busy tone)
Does anybody know what I could try in order to get my second dial tone so I can go to the PSTN?
I would need 8 in order to connect to the Harris PBX and then * to use these lines to go to the PSTN.
Thanks a lot in advance!!!
