7964 & 6941 phones on FXO unable to pick up more than 1 line

[tlmaclean67]

I have a customer with phones attached to FXO ports off of a Cisco Communications manager express.  They are 7964 and 6941 phones.  They can not answer their 2nd call (when they are on a call).  They can see the line ring, but can not put the first line on hold and answer the second.  They phones are set as dual line.  Is there another configuration that needs to be done.  I have to access the phones either from CLI or from Cisco Communications professional.

Thank you for your help.

Hi Teresa,

i do not think MCPL is supported on SCCP 6941 phones on CME ver 9.0 even though you can try the max call per button command given below.

Multiple Calls Per Line

Cisco Unified CME 9.0 provides support for the Multiple Calls Per Line (MCPL) feature on Cisco Unified 6921, 6941, 6945, and 6961 SIP IP phones and Cisco Unified 8941 and 8945 SCCP and SIP IP phones.

Before Cisco Unified CME 9.0, the maximum number of calls supported for every directory number (DN) on Cisco Unified 8941 and 8945 SCCP IP phones was restricted to two.

With Cisco Unified CME 9.0, the MCPL feature overcomes the limitation on the maximum number of calls per line.

In Cisco Unified CME 9.0, the MCPL feature is not supported on Cisco Unified 6921, 6941, 6945, and 6961 SCCP IP phones.

Cisco Unified 8941 and 8945 SCCP IP Phones

Before Cisco Unified CME 9.0, Cisco Unified 8941 and 8945 SCCP IP phones only supported two incoming calls per line and a third channel was reserved for call transfers or conference calls. These phones were also hardcoded with ephone-dn octo-line, huntstop-channel 2, max-calls -per-button 3, and busy-trigger-per-button 2.

In Cisco Unified CME 9.0, you can configure the ephone-dn dn-tag [ dual-line | octo-line ] in global configuration mode and the max-calls-per-button and busy-trigger-per-button commands in ephone or ephone-template configuration mode for Cisco Unified 8941 and 8945 SCCP IP phones to configure a DN and enable the number of calls per DN, set the maximum number of calls allowed on an octo-line DN, and set the maximum number of calls allowed on an octo-line DN before activating a busy tone.

For configuration information, see the “SCCP: Configuring the Maximum Number of Calls” section.
